runs hot, overclocks like a mother, performs excellent, cheap.
amdxp is great for gamers because the higher (much higher, in fact) clocked p4s and its comparably rated amdxp chip are pretty much even give or take a few frames per second. 3dmark scores are always very similar... although p4 seems to take top honors over the flagship xp.
however, for video editing and music encoding (anything that takes RAW horsepower), the p4 stacks up better than anything out of the xp line... you need the amd64s to go toe to toe with the p4s in this regard.
i have an amdxp 2500+ and i often have it overclocked to around 3500-3600+ speeds... watercooled of course!
