I dont know if in other parts of the world if you have P4 64bit but in australia we do along with amd64. I recently got a new computer with the new P4 (rare in australia at the moment) and it is 3.0 ghz HT (Hyperthreading) (800 fsb). When i can compare that to the new amd 64 with only 2ghz no ht. We only got the 64 bit to prepare for the futrue technology of XP 64bit. Anyone else got the P4 64 or amd 64 if you have anything to say about comparing these to say it. I reckon the p4 is better because it has a higher ghz.
