mt_lutxy, mt_lut, FFmpegSource use a lot of memory. 8 threads will eat your memory faster.

Also 8 threads on i7 is useless. You will get slow execution, because most time the processor
will switch threads and wait for spin locks.
I use GraphstudioNext to benchmark my scripts (Psharpen, Awarpsharp, Vaguedenoiser etc) and on my 2600K with Hyperthreading I get a considerable performance improvement having 8 threads over 4.
My recommendation would be to test this for yourself.
