So here is the thing, I'm running an E5300 @3.5Ghz with an HD4870 512MB, 4GB RAM, 500W zalman psu. the upgrade itch got me, would Igain anything upgrading to an 2500K platform using my HD4870? upgrading the Videocard wont get me much because I'll be bottlenecked, Iwill eventually upgrade the videocard in the winter, but for now will Isee any proformance increase in day-to-day apps and games?
