Re: I want buy new pc.
Yeh it should be fine. The dual core will offer more performance for games clock for clock (e8500 is better than say a q6600 @ 3.16). If you think you use a lot of heavy stuff and multiple programs (not just that you have music running in the background) then i would go quad, you'll only see a slight decrease, but the quads will cost you more if you want a higher clocked one, otherwise you can get an aftermarket Heatsink and overclock a q6600.
Back to stay?
