ok, I plan on buying a DX4860-UB32P tomorrow for 150, not bad I think, but wanna know whats the best CPU for this machine.. I know the powersupply is junk that's a given, but want to turn this into a gamin machine... I currently have a dell xps 410 that im using now with a q6600 in it.. and a 5670 amd gddr5 1gb sapphire, is this gonna be a huge upgrade from what I got now?
