"CPU matter in gaming, the MOST! "
Actually, he was and is quite correct....the gpu does indeed matter most in gaming.
Once at high res/settings, the way most people play when they have 7900GTX cards, the increasing cpu clockspeed causes severely limited gains to the tune of about 3-4%, as long as you have enough processor, around 2.2G (A64 types)....
Witness that fact that a relatively inexpensive processor like the A64/3500+ is outframed in FEAR by only 1-2 fps at 1280x960/4xAA when compared to an FX57, still the top-dog single core cpu. Once at 2.2GHz or so, the extra 200-600 MHz gains one only about 1 frame per second.
Which will outperform (i.e., produce acceptable framerates at high resolutions) the other in FEAR, COD2, BF2, etc...
An A64/3200+ ($160) equipped with a 7900GTX ($400), or an FX57 ($800)equipped with a 7600GT ($200)? (Still think the processor matters most?)
If you feel that is worth paying 4 times the price or OCing the crap out of your cpu for a single extra frame/sec...more power to you.
