Have you installed any new GPU drivers recently? Game might not like them.

Hey pal, yes matey I've installed 306, 301, gone back to 285 doing clean installs each time.

Ok I seemed to have fixed the problem by applying a slight overclock on each card from the standard 701mhz to 797mhz on air, seems to be running sweet aswell, I think my cpu aint helping much, going to try the new Bulldozer 8150 thanks for your reply Richard.

You definitely need a new CPU (either a X6 or bulldozer) and if possible, liquid cooling in order to OC the CPU to at least 4 GHz so you won't bottlenect those GTX 480s in SLI.

Thanks for the reply pal, yea I have ordered the AMD Bulldozer 8150 but wont be here till friday 28th september .
I have a Corsair h60 too, this should be ok shouldn't it?

Thanks again.
