i'm currently running what is in my sig, e4300 @ 3ghz and evga 8800GT 512mb SC stock. i upgraded from a 19" screen to a nice 24" and obviously my gaming performance obviously took a hit. for the most part i play all types of games including the latest and greatest like crysis, but don't necesarily have to play at the highest settings. having said that, would i benefit from a cpu upgrade? upgrade my vid card? how about an sli mobo and another 8800gt? i'd like to use as much as i can from my current setup and would want to keep upgrades under $400.
