hello all, dont know if this is the right place for this... i use my pc only for gaming... in particular Dungeon Siege and Doom3. i have a 20" cinema display that i use for both my mac and pc via dvi kvm switch. dungeon Siege gets around 30-40fps, and doom as well. its a shuttle SS56Gv2 with Pentium4 2.4ghz and a radeon9600xt AGPx8. if i wanted to improve gaming performance, would i benefit from a faster (3ghz) cpu? or faster video card(x800pro)? or both ? any insight is appreciated.
