Could it be new drivers issue, or CPU bottle neck? Not a very big jump with a high OC compared to my 5970 card stock vs high OC.. Am I missing something here...
Can you run Vantage on the extreme preset perhaps? If there is no noticeable gain from stock and that overclock on the extreme preset then my guess is a driver issue / system issue. It is possible the performance mode is bottlenecked as 1680x1050 is a joke for a dual gup card like that. I'd test heaven and 3Dmark11 as they both scale quite well ( much better than Vantage )
