Thanks for that, it's working now. WinTimer puts it at 14.32Mhz. I just ran a Metro 2033 benchmark using it's tool. Seems to be the exact same performance. I did benchmarks for a couple of my friends 2-3 days ago, so I have the results for accurate comparisons. Minimum and average FPS are within the margin of error. I'll play BF3 MP and post back. What realistic difference should I be looking for? I don't care about synthetic benchmark improvements.
