I think the AMD 64 is nice, but not sure of it yet. i think ill stick with a 32 until intel comes out with a 64 to see where the competition takes them both and until more software comes out to support 64bit systems . I may ( if i can spare the money ) get a NVENTIV Mach 2 phase change cooler for my CPU. i have seen a P4 3.2 running stable at 4.3 whith the mach 2 cooler ( thats what im talking about )
