Have you overclocked your CPU? I don't know how demanding this game is on the CPU, but you may be hitting a CPU bottleneck that can be remedied by overclocking.
Under Power Management for Windows, are you set to High Performance?
I do know that I had to reduce the IR and AA/AF from what I usually use as defaults. Did you try bringing down the IR/AA/AF a little bit to see if you were getting GPU bottlenecking?
