Been running Win 7 on a refurbished Dell GX280 tower for a few weeks now. The Windows Experience shows that my processor is the weakest point on my system. I found a few places that sell a 3.4Ghz 800fsb 1m cache Socket 775 processor for not to much. Will this processor work in my system with a 2.6Ghz processor? All other specs are the same. Anyone have experiences upgrading this system?
