I want from XP sp3 to win 7 ultimate 64bits.

Can avisynch use by encoding with x264 36 threads??? My hardware is dualsocket workstation with two 6-cores xeons. So its 12 logical cores = 24 virtual cores *1,5 = 36 threads.
Or is avisynch in this case somehow bottlenecked?

Witch version of avisynch should I use? I don t want use GUIs, coz I m now happy with x264 encoding with cmd.

avisynth is limited to 2 gb of ram as 32bit application (32bit builds), so if you would to use it with 36 thread probably won't work with memory-hungry filters.
instead using avisynth in single or double thread should work correctly

set's 64bit build shouldn't have problem but many filters or plugins are still missing

In 90% I dont use filter just simple script like this

DirectShowSource("F:\titans.grf",Audio=false,Fps=23.976)
ConvertToYV12()
Spline36resize(1920,816,0,132,0,-132)

So I will use 64bit build, coz my system has 12GB memory.
Do you think everythig will work ok without any issues?

Should work fine. If anything you will probably bottleneck your decoder ;)
