One note: while running a 64-bit OS is nothing more than a geek penis-size contest (one in which I happily compete
), the Athlon 64 processors are amazing. Totally aside from their ability to run 64-bit and 32-bit code natively, they run games faster than any other processor out there--and generally cheaper than their Intel counterparts. Great chips. My current processor is one, and my next one will be too.
