I would like to know why 64 bit processors are better/worse than there 32 bit (or however many bits they have int the p4's) partners. Would my current p4 3.2ghz run slower than a 64 bit 1ghz processor, and if so why? I ask this because im in the market for a new mobo and cpu, and I hear allot about the amd 64s and how great 64 bit computing is. However, I have also heard that we dont really have any use for the 64 bit cpu's quite yet. Also, if amds 64 bit cpus fare better in preformance than intels 32 bit, why doesnt intel make 64 bit cpu's?
