AMD or Intel - Which Re Encodes Faster?

[majagua]

I am about to buy a new system, thinking of a performance gain in the re enconding operation in REMPEG.

I know that AMD has it's strong points in some type of apps and intel has other strong points (like for example, in gaming). So for the specific type of application that REMPEG is, which processor is faster????????

[NeVeRLiFt]

I'm a AMD man myself ;)


Here are two links that have honest reviews and benchmarks, go research and read. AMD cpu's have stable mobos out now, and for the price vs performance AMD kills Intel :p

It takes P4 @2200mhz to tie or beat my computer LOL


Here are the links...

If you have the money to splurge get an Intel. But for more bang per buck get an AMD. I am overly happy with my AMD.

[prot0vision]

The software you use needs to be optimized for whatever chip you have, AMD or Intel, in order to see full performance (3DNow, SSE, etc).

Up until recently, the divx 5 codec was optimized for the Intel chips, but now has AMD support.

Personally, I'm in the AMD boat, like others, best bang-for-buck. Just glad that programmers are optimizing for AMD as well as Intel.

[Neo Neko]

Yeah with my Anthlon XP I am only missing out on SSE2. I have MMX1/2, SSE, 3dNow1/2, etc. Just SSE2. Lets see an Intel user say that! hehe. Not all implimentations are equal. But can it hurt to have the most? :)

[buba king]

the p4 is alot faster on encoding then any amd chips. (unless you get a dual board :p )

[TheCocaCola Kid]

It all depends on what type of money you are wanting to spend really.

I have a dual Xeon (P4) 2.4Ghz system with 4 Gb of redundant memory (3Gb usable, 1 Gb is redundant), all SCSI U160 73Gb 10K hard drives, 1 gigabit NIC, and more toys than you can shake a stick at added on this baby.

THERE IS NO AMD SYSTEM OUT THERE THAT CAN RIP AS FAST AS THIS!!

I can rip a movie at almost real time! But I also blew ALOT of coin on the system (but I resell it to a customer when something new comes along so who cares!)

If you want awesome performance for a lower budget well buy AMD but have LOTS of fans and learn to tolerate the fan noise. Mine you can hear a pin drop next to it but it also costs 6 times more too.

Just my opinion and I am sure a few of you AMD people will trash me over this but I build both NOW and will build anything anyone wants but I still prefer Intel because of its reliability. How gives a crap if they are more expensive, its only money and like your going to take that with you when you die. You also earn it to spend right?!? Why not spend it on what you love to do!

:)

[SirDavidGuy]

But most people don't have possession of your limitless pockets.

For instance, you can get a dual processor AMD board, with two processors, for the same price as one of Intel's fastest. It'll blow away the Intel. Sure you can get a faster, dual-processor intel board, but for the extra money you spend, you could get another computer.

[TheCocaCola Kid]

But when you already have 10 in the house.... blow it all on one because it saves space that way! LOL

I need to start building rack systems and setup a couple of racks!

I agree with you on the cheap AMD thingy though.

[Neo Neko]

My AMD can encode video in real time. And it is quieter than my PII 400. :)24~25Fps 640x480 DVD video. :) Step up to 720xXXX and it goes to 20~22Fps. I blew big bucks on this sys! A whole $350 on it! :) Sure I used my old DVD/CD ahd 30Gb HDs. But everything else was new. ;)

When it comes to Floating-Point power the AthlonXP kills the P4 ;)

[chainsaw135]

Yeah i must say i have two computers, both of them are xp's reason is cost and also performance.. i see it as i wanna get more for my buck and you do with amd.

[Emp3r0r]

Thats it, I worked my ass off this summer and I'm finally upgrading my P2 350 overclocked to 392. I think I will go with Intel since I haven't used a P4 machine before but I have faith in Intel. I've used p1, p2, p3 900, p3 1ghz, Athlon 550, 800, XP1900, XP1800. I'm not impressed with AMD yet, nforce is cool, maybe nforce 2 will change my mind but as soon as the 2.8 p4 comes out I may snatch up a 2.4 if they drop enough in price. I just wanna make sure I get the best. thats what I did 3 years ago and I plan on doing it again. I just wish SCSI was cheaper. the XP is the fastest I've ever used though. I just wanna test out a P4 to compare.

[NeVeRLiFt]

Wrong!
When it comes to pure floating point the AthlonXP kills the P4.
Thats why it takes a P4 running up to 700mhz faster sometimes to beat a AtlonXP in certain benchmarks.
Head over to www.hardocp.com or www.anandtech.com and do some research.


As for my computer now, it takes a P4 running at 2200-2400mhz to beat it. I have no money in this computer and its rock stable and super fast. ;)
I see myself getting a AIW 9700 and bigger harddrives in the future and thats it for now.

[dvd2svcd]

I have attached the SiSoft results in my computer specs (see signature link)

But there is no doubt, you get more for less when you go for AMD.

[NeVeRLiFt]

If you take the time to look carefully you will see Sandra uses SSE2 for the P4 and SSE for the AthlonXP on the Multimedia test.

On the CPU test its all good it shows two numbers for the P4 and the the one thats not for SSE2 is the one to compare to the AthlonXP ;)

Now you see how badass the AthlonXP is when it comes to Floating-Point Power. There are special tech benchmarks that show this.

I use Sandra 2002 Pro
And my computer beats the P4 2600mhz :p and im running around 950mhz slower .... tell me thats not good.

[dvd2svcd]

I use the same version of SiSoft. I have proved Intel to be faster than AMD you haven't no matter what you say we need some proof. (And same time try to beat the ram speed)

[Acaila]

Intel is faster for video encoding, but IMO definately not worth the price difference.

Unlikely. Mine doesn't even win out over a P4 2.6GHz, only a 2.4GHz (on a single-cpu test that is). Show us some Sandra results to prove what you are saying.

@dvd2svcd:
That is indeed a kickass ram speed :D

[NeVeRLiFt]

On the CPU benchmark the AthlonXP has one score. The P4 has two setup like this xxxx/xxxx the first one is the one to compare ;)
come on guys dont make me bring in links from review sites.
This is for the Floating-point on the CPU benchmark look carefully.


The only time the P4 does good is when the software uses SSE2.
And as for Rambus (what a joke) give me a 400mhz DDR any day :D

The P4 has weaker Floating-Point are the same as a P3.

And now you see how even at 2600mhz the P4 gets beats.

[NeVeRLiFt]

CPU Arithmetic Benchmark

P4 looks like this for the Floating-Point
Whetstone FPU/iSSE2 xxxx/xxxx


The AthlonXP looks like this
Whetstone FPU xxxx



Come on guys every review site has pointed this out, why else do you think the AthlonXP running so much slower in the mhz beats it on some benchmarks are more than holds it own!
Also the Lvl-1 cache being 8kb hurts the P4 very bad....

[dvd2svcd]

You are all talk and no action (Do I ever know the type). Prove it. Show me your own tests. Show me where your AMD system beats mine.

[NeVeRLiFt]

You like that dont you?

Just look at it, its already there for you ;)

Read my posts you will see dude.

[NeVeRLiFt]

In the CPU benchmark compare the Whetstone FPU of the AthlonXP to the P4. You will see that a AthlonXP @ 1533mhz ties the P4 @ 2600mhz

I dont lie dude and the graph shows you this so get over it.

[Acaila]

Ok, so you are both talking about two different things. dvd2svcd is talking about real life benchmarks, while NeVeRLift is talking theoretical. Yes, AMD beats the crap out of Intel when you don't look at Intel's SSE2 score. However you can't turn off SSE2 for a program, so there's not much sense in comparing benchies without taking SSE2 into account.
Since this thread's creator asked what is fastest for video encoding, and since at least DivX5 and XviD use SSE2 optimizations the only answer here can be: Intel is fastest.

[NeVeRLiFt]

@Acaila

I proved my point.
And anything needing floating-point power will do better with the AthlonXP... take Seti or Folding for example ;)
The AthlonXP cleans house and dominates in the quickest times.
And there are some Floating-Point only benchmarks that really show just how strong the AthlonXP is :D


Sorry to ruffle some feathers there, but the bottom line is the P4 has Floating-point like a weak ole P3 :eek:

[dvd2svcd]

[NeVeRLiFt]

As I thought blind and full of intel :rolleyes:

[dvd2svcd]

How can you say that I am blind when you haven't given me anything to see? Enough BS. EOC.

[NeVeRLiFt]

Dude I got nothing against you are the P4, but the truth is the truth and the P4 has weak FPU. Its still a good cpu because of the design and the bandwidth it can use.

Here is a very trust worthy site and super good review
(HardOCP keeps it real)

http://www.hardocp.com/article.html?art=Mjc1LDE=


Remember the P4 is running 700mhz faster.... and we want compare prices ;)

[dvd2svcd]

No we do NOT want to compare prices! Read the topic again DUDE!
AMD or Intel - Which Re Encodes Faster?
And that is without a doubt intel.

[NeVeRLiFt]

Only if the software uses SSE2..... otherwise the P4 is as weak as a P3 :p

[dvd2svcd]

Your point being ?!?

[NeVeRLiFt]

LOL

The point is, for the money the P4 is a weakass POS :sly:

[dvd2svcd]

Money isn't the issue so stop rambling about that. No matter what the costs, the fastest P4 is beating the fastest AMD, a weak FPU or not, SSE2 chrushes AMD in the dust, that is just how it is. Live with it.

[manono]

Hi-

And if you're willing to overclock, I think a case can be made for the Northwoods matching the Athlons dollar for dollar, and fps for fps in encoding speed. You get a 1.6A or 1.8A Northwood (costing about as much as AthlonXP 2100+ or 2200+ CPUs), an inexpensive SIS based mobo, some decent DDR SDRAM and overclock the heck out of them and I defy any Athlon to match them. Of course this may come to an end when the next generation of AMD CPUs comes out.

But I think you're fighting a lost cause butting heads with dvd2svcd and his system NeVeRLiFt. That Rambus memory of his is some kick-ass stuff.

If you're curious about real world encoding speeds for different systems, go check out the CCE Speeds thread down in the Advanced DVD2SVCD Forum.

Money is an issue.

Look at the fastest Athalons price compared to the Fastest P4 price.
Double the Athalon's price (By getting two), and it's still cheaper than the fastest P4. 2 AMD 2000+'s will beat the fastest P4 into the ground.

[dvd2svcd]

True money is an issue, but not in this thread. Look at the subject:
AMD or Intel - Which Re Encodes Faster?So I say again, disregard the money issue in this thread.

[Emp3r0r]

besides, floating point doesn't make a cpu better. ok, so you have two math nerds, one is very fast and cheap and calculates numbers really well and doubles as a high tech space heater. the other calculates numbers decently well, but also is smarter. It is optimized for what computers do these days and does it effeciently while staying cool. Intel has put a assload of money into an optimized architecture. In my opinion, above 2ghz, cpu architecture becomes the selling point for me.

[Zhnujm]

please remember, majagua asked for the speed of rempeg. it doesnt use sse2 (or does it?). and as you can see in dvd2svcds post the fpu of the xp2200 is twice as fast as that of the p4 2.4 .
to find a useful answer we should test the speed of rempeg and not compare any useless benchmarks.

[NeVeRLiFt]

@Emp3r0r

My AthlonXP idles at 32c :p

[NeVeRLiFt]

@manono

Rambus gets beats by DDR when its running at say 333-400mhz DDR
so maybe you head over to some review sites and see for yourself.
(Are its more than holding its own) and the new chipset from nvidia called the nforce2 already talks about supporting 400mhz DDR and the new chipset from VIA does to.

And lets see..... have to make sure software has special code for my weak CPU (SSE2) or have a strong monster CPU that has it all and does not need special software. Ya I like my AthlonXP and www.Tomshardware.com done did alot testing on encoding and showed how strong the AthlonXP was.

[dvd2svcd]

You should really read the article about DDR versus Rambus on thg again. Rambus PC1066 beats DDR400 on every Memory benchmark! And on the other benchmarks DDR400 and Rambus PC1066 is taking turns on which is fastest (actually PC1066 wins on most tests). So please stop these false statements of yours.

[NeVeRLiFt]

Ya the DDR ram more than holds its own against Rambus ;)
again we want compare price.... :p
And I dont use THG for reviews.... I use www.HardOCP.com and www.Anandtech.com

[dvd2svcd]

I really don't care about what you're saying anymore. You just can't admit when you're wrong. So sad. And first you link to tomshardware and then you say you don't use it. You are pathetic.

Just because I provided link for you chummers dont mean I use his site for reviews....
And you can act like a intel zealot all you want :p

Smart people know for the money the P4 and Rambus suck! :devil:

[chainsaw135]

@neverlift i have all amd chips in my machines, but i'm not about to sit here and call someone stupid because they dont. Or state that i'm smarter for it. I would hope you apologize for your behaviour as i'm getting tired of seeing threads turn from a nice innocent question in to a brawl. If this dosen't stop i'll lock the thread period. I hope you understand and i hope your reply is much nicer then the ones i've been seeing.

[NeVeRLiFt]

I dont recall calling anyone stupid.... but I think I knocked someone off there P4 high-horse if thats what you mean.

Everything I have said has been true....


Special notice:

AthlonXP 2200+ 1.8GHZ = $211.00

P4 2.53GHZ = $596.00


Fastest DDR = $205.00

Fastest Rambus - $379.00


Now go read the reviews and look over the benchmarks and lets leave it at that ;)

[chainsaw135]

Well i could put my 2 cents in about my feelings on the whole thing, but right now i'm concerned with people that start taking pot shots at others, just because of the persons opinion. Thats why my reply directed was towards you. I see you belittle someone because he likes P4's over AMD. Here is a quote from your post which i find it to be on the border line of tolerable and a bit annoying "Smart people know for the money the P4 and Rambus suck!" And not only that but i ask you very nicely to tone it down and you take a little shot at me, i dont appreciate that.

[gerti67]

Oh boys, please stop bickering! - Like Chainy already said, I can't stand it anymore.

What's this quarrel all about? The starter of this thread just wanted to know what machine is fastest in video encoding using REMPEG mainly. So there's no other benchmark necessary than this program itsself - so that you can say: "Yes, this machine is faster with it."

And if you're so keen on benchmarks NeVeRLiFt why do you ignore this one (http://www.tomshardware.com/cpu/02q2/020610/index.html)? You know, I myself own a AMD mainly for budget reasons but I don't make a religious cult out of it. You have to face the facts. It's true, when the first AlthlonXPs hit the market Intel had nothing comparable concerning speed and raw power. But time has changed man, now Intel has gone one step further and the new P4 just (b)eats the latest AthlonXP (2200+) in nearly every real world benchmark - see the link above - I guess 32 benchmarks with a variety of programs is what I consider a real life bench.

Hey, and this can change again in a few month when AMD releases the "Barton" with its 512K cache and perhaps SSE2 capabilities (although they say it's only the bigger L1 cache and the 64-bit CPUs will have SSE2 - but who knows). This happens in life from time to time. And Intel wouldn't have been where they are now without AMD and vice versa.

And concerning money, you know some people just calculate this a different way. If I buy a new PC only the costs of the core components (mainboard, CPU, memory) are about 3 times higher when buying the latest P4 instead of buying the latest AthlonXP. But concerning the overall costs for the whole system when speaking of a top notch one then it's only marginally higher (about 600$). And you can't get two AthlonXP systems for the price of one P4 system like some people state here because only the core components is not what I call a runnnig system - let alone that video encoding is not predestinated to run paralleled over a network.

And some users just value their time in money (especially developers and nearly all people that earn money with their PC as well). When you take this into consideration, and you can finish your work/testing/whatever one hour earlier per day and you value this hour with only 10$ each. Hmm, guess what, after 60 days of work/testing/whatever the one that bought a P4 seems to be smarter to me. :sly:

Just my (in)sight on this topic,
Gerti

[NeVeRLiFt]

Ya whatever floats your boat dude.
I think people have more than enough info in these posts to make a wise choice ;)

I would build me a Dual CPU AthlonXP 2200+ setup and be more than happy and with the extra money I have left over I will goto SeaWorld :D

[Stabmaster-Arson]

DVD2SVCD said this
"You are pathetic."
Thats not nice.

Neverlift did not flame yet or call anyone stupid in fact. (Just adding my 2 cents cause mod dude picked on him for some reason and not the other guy). Just saying his point of view.

Homeboys both need to calm down a bit though and we dont need any blatant flame, but discussing a differencing point of view isn't sdo bad.

[NeVeRLiFt]

I dont let it get to me dude, but thank you. :)

I try to help people in my posts and always tell the truth and give good advice to the best of my ability.

If you look over my posts you will see I get flamed and attacked alot ROFLOL all for trying to make some helpful posts on how to make good 1cd rips.

[dvd2svcd]

If you people would read the entire thread you'd see that I have pointed to many sources that disproves neverlifts statements. He claims to be telling the truth, but he does not. Maybe he thinks he does, but he doesn't. And the fact that he cannot accept fact make him per definition pathetic, or at least his stubbornness is. I truly feel sorry for the people he has mislead in this thread. And apparently the only arguments he has left is the money argument, which is not one to be considered in this thread (again read the subject).

So, to all who thinks I am the bad guy, I urge you, read the entire thread and I am sure you will agree that neverlift is indeed pathetic.

He is allowed to his opinion ofcourse, but that does not make what he says the truth.

And if you read the thread you will see that I more than once agrees that AMD gives you more bang for the buck but that does not make it faster.

I know that neverlift is one who never stops rambling, so for this thread to end I quit now and let neverlisft have the final word if he so wishes. I have said what I wanted to say and enough is enough.

[NeVeRLiFt]

Peace
And I think you said it best "AMD gives you more bang for the buck"

And the benchmarks prove the AthlonXP more than hold there own.
Whats sad is the P4 needs 700mhz more than the AthlonXP to tie or beat it.

[dvd2svcd]

Peace.

And for the record, I never disputed those two statements :)

[auenf]

heh, didnt i say in a amd v intel thread somewhere that its fighting words?

but in summary, each CPU has its own benefits:

Athlon: Fast ALU/FPU, 3dnow! (and derivitaves) support, SSE support morgan and pal and newer), cheap (ish)

P4: Fast ALU, SSE and SSE2 support, runs cool, very good motherboards and chipsets availble.

and they all have their disadvantages too:

Athlon: runs very hot, still not a chipset available for it that matches the i845 that the P4's can get.

P4: slow FPU (intel is trying to push SSE2 rather than raw FPU), expensive(ish)

and please, no flaming, im sure the forum doesnt like the scars.

ReMPEG2 XP1800: 90ms for a full pal frame (720x576) at 80% bitrate

if now somebody can post results for a P4 or faster XPs we can finally answer the thread starters question ;)

[ppera2]

Why always such threads AMD vs Intel ? Especially it's not good idea by video encoding where memory bandwith has very great influence.

I just want to say that good MB with fast memory is much more important here than CPU itself. And if you are limited with money it is essencial.

[theReal]

I just want to say that good MB with fast memory is much more important here than CPU itself.You're right - but then there's the question: which chipsets are better right now? Those that are available for Intel, or those that are available for AMD? ;)

[Emp3r0r]

I will be purchasing a new motherboard, cpu and memory in the next couple of weeks and what is funny is this thread has not one bit helped in my decision. The following things have me in a split decision.

AMD is faster for cheaper
Intel can match that with northwood overclocking potential

AMD is about to get DDR400
Intel is about to get DDR400

AMD is initially hot
Intel might be just as hot after overclocking

AMD 2200 will be about $211
Intel 2ghz will be about $221 (yet faster after FSB overclock)


So, as you can see, this decision is very hard. At the moment I am leaning towards P4 because it is better @ encoding: http://www6.tomshardware.com/cpu/02q2/020610/images/image012.gif

Whats sad is the P4 needs 700mhz more than the AthlonXP to tie or beat it.
If these CPU's could be compared based on MHZ, then the Athlon 1.8 is almost 80 dollars more expensive than the p4 1.8. Where is your argument now?

[gerti67]

@Emp3r0r:

Hah, believe me - it's impossible to make the right decision when it comes to buy and assemble a PC! I learned that over the last years. ;)

After weeks of carefully reading tests, suggestions, reviews and comparing prices you buy your "dream-machine" and guess what - right after you have assembled it at home one of the following things happen:

- the prices of the CPU you just bought drops by 50% or the price of the other CPU brand you haven't bought because it was to expensive drops.

- this applies to the memory also and any other components.

- the mainboard manufacturer of the brand you just bought ships a new version of the mobo you have just put into your tower case with a lot of new features at nearly the same price.

- Intel/AMD announce a mind-boggingly new technology, they claim to be the (only) way for the future - and it sure is not compatible with the hardare you just bought.

- ...

So you see you can never win this race - you can just pray that it doesn't catch you the real hard way and all points I mentioned happen at the same time. :D

Just from my experience (and don't take it too seriously),
Gerti

[NeVeRLiFt]

Well if you have a AthlonXP @ 1.8ghz .... it takes a P4 running at 2.5ghz to even tie it or beat it in benchmarks :p
Duh!!!

[chainsaw135]

gerti67 is totally right about him stateing its so hard to buy because it seems like right after you purchase something it drops in price buy 50% or more. I remember when i bought my geforce 3 card it was going for $167.00 U.S dollars. Not even 7 days after that it dropped down to $110.00 and thats not the first time something like that has happened.

So FPU power is still important and this K7 boy is very strong with its 3 FPU units ;).

Good post!

Most people just dont realize how weak the P4's FPU power is ...
And SSE2 cant make up for that. Thats why it takes a 2500mhz P4 to beat a 1800mhz AthlonXP.

well, the 1800mhz Athlon XP beating the 2500mhz is both using FPU, with SSE2 properly implemented would make the P4 toast the same clock Athlon, but dont count on that sort of implementation becoming mainstream until both cpu's support SSE2 (which wont happen, cause Hammer will be first AMD chip to get SSE2

Don't know about audio but decoding video with DVD2AVI and MPEG2DEC is mostly done in SSE assembler, usually integer. This means the compiler optimizations have much less affect but my own experiments in adding SSE2 optimizatons made (IIRC) about a 20% difference in decoding speed, or a 10% difference in total reencoding job time, on the same P4.

And I think XviD has some similar SSE2 optimizations now, though they may not be turned on by default.

This things can happen mostly with Sandra & Company SYNTHETIC benchmarks, not in real life problematics.

Never seen this scenario,
Neither at those discording benchmarks between www.tomshardware.com and www.anandtech.com (and look at the rest of the www and will see as test results are very different... especially gaps mooore flatten between P4 and K7, when in favor of the one or the other...)

about same clock...

Do you imagine the performance of one Athlon at same clock? Sadly, at this point even a P3 Tualatin could be faster than P4 with 95% of software applications.

The reason? P4 is good but isn't so genuine complete package as P3 or K7.

The first reason of reputation for an innovative CPU would be the overall (ON ROAD) gain in superscalar/RISC core performace, secondly the SSE1-2-3-4-5 pumping patches.
To me, P4 doesn't seem so genuine as its digital ID claims.


Look at the "package" incredible similarities :D:

Athlon: overall genuine and flexible native superscalar performance
No particular speed flaws to run old, new, various conditions:
think "Ferrari + Bridgestone tyres"

Pentium 4: brute force boost but very fluctuating gain performance.
Very promising and technically potential package, though particulary suitable for certain "statistically most common" conditions:
think "Williams + BMW + Michelin tyres"

Just finished setting up my AMD 2200 XP(!!) with 1024mb DDR!! Can't wait to try this shit out. Took about 24 hours rempeg2ing on my last system

When someone tests P4 Xeon processors against a Dual AMD system then I am willing to talk.

My system is P4 XEON (Dual) and no AMD system out there can touch it I know because I build lots of them for my customers and none of the hottest AMD dual systems I built can even touch my system.


So test those two against each other and post the pics of the benchmarks and watch AMD hang its head in shame.

My opinion AFTER seeing tons of proof first hand!


And yes I know Intel P4 Xeon cost a ton more than AMD but if you want the good toys you always pay more. ie: Camaro compared to Ferrari!

So flame away I have thick fire proof skin.

Xeons are of course better than any AMD or normal P4.
But usually, people don't mean "dual Xeon" when they talk about buying a P4 system :)

[TheCocaCola Kid]

I did and it kicks AMD's slow little butts back into the dark ages!

Xeon from now on baby! They are getting quite cheap too in Canada.

P4 2.0Ghz $300 Can

P4 2.2Ghz $400 Can

P4 2.4Ghz $$870 Can damn they dropped again, I paid $950! Argh! Oh well, that's the tech trend!

And don't forget when you transfer that to US $ you could get the P4 2Ghz for $200 USD.

And yes these are wholesale prices I get. :D

Sorry you feel that way.

Have you tried not reading it!!!!?


LOL

PS: Mine isn't BS!

ppera, I guess you'd love the amdmb.com forums, especially the "processor discussion" ;) :D

@theReal: I am glad you gave that link :) I love this thread:

great thread. zealots amaze me sometimes.

I wished I could say that this thread has served its purpose and in one way it certainly has: the "what's best" discussion is just not going anywhere.

allow me to quote from the forum rules: Do not ask "what's best" because this question cannot be answered objectively. Each and everyone has their own view about what's best in a certain area. The best is what works best for you!
