Yes, AMD is better for gaming, BUT, did you know that Intel's cache speed is actually the same as the CPU itself and the AMD is half?
So say you have a 3Ghz P4, you get 3ghz of cache speed
but, AMD = 2.8Ghz XP CPU = 1.4 Cache Speed.....
You do the math...Only reason AMD does better in gaming, is becuase of the dye in the CPU itself....the P4 takes around 1.4 Million DYE while the XP is at about 1.1 Million dye....
just a nerd's .02
