My son wants to build a nice gaming computer. His friend built one with an AMD Athlon 64 3000+ Socket 754. Seems ok. But it was close to half the price of my Intel 3.4GHz Northwood I used in my computer. ($160 vs $310) The AMD doesn't even mention GHz, how are you supposed to compare. Also, their gimmick is the 64 bit computing, but do any games use 64 bit yet? Does anything? Is there some disadvantage to AMD?
