uhh.. ur wrong..
P4's are specially made for HOME COMPUTING, w/ or w/o htt! (hyperthreadtech)
Xeons, Tualatins, and Itaniums (sp?) are specially made for servers..
Hyperthreading WONT boost game speed, ever, unless the game is designed for it. Hyperthreading is good for multitasking, and it should speed up boot time.
