it kind of depends what you want to do with the cpu, or atleast das wut ev1 on just about all forums say
the p4 is for dual processing and all that good stuff for buisnesses, and music industry etc...
the amd cpu's as a whole are for gaming, they have always been lower temps from what i here, and amd actually wants ppl to OC the cpus and all that good shizzy for gaming
im not trying to state that all as hard core facts, just what i read in forums anyways that said
amd pwnz cuz it pwnz for gaming and tahts all that matters in this world
