A new CPU would help allot though, a quad clocked over 3ghz would open up the GPU more and with today's games it would boost performance quite allot, but it's not cheap even on a 775 to go to a quad from the c2d. Ideally would like a q9450, but meh they still go for £200 new and £140/£150 second hand, if going to upgrade to that might as well just go full out on a i5 or something but then comes all the added cost of that to.
