Im running a Intel core duo 8500 right now, i think the base speed is 3.16 or so, im planning on possibly building a new system for gaming only, would a quad core intel chip be better even though the speed is lower than i have now? What would I upgrade to to improve performance? im presently running with 4gb of ocz 1066 ram and 260 gtx card on an asus p5ql pro board w/ xp pro
