go with a P4 if you arent a hardcore gamer. I upgraded from northwood 3.0 asus P4C800 DLX combo to an an a64 3500+ asus NF4 SLI combo, and it is very noticeable to me that in normal everyday usage, the P4 is faster.
Hyperthreading makes your PC a whole lot more usable if you do more than one thing at once. like for instance when I rip or encode a dvd, I can do other things like browse the web. with an a64, it's so laggy that its pointless. little things like that add up, and once you get used to the smoothness of hyperthreading, its hard to go back.
my coworker has an even faster cpu than me (fx-53) and he is going back to intel because he misses the better multitasking capabilities of a P4.
