Great, thanks for the response.
Another question, I play World of Warcraft, when I am hanging around, I notice my GPUs are running at only 50%, but I am only getting around 30 fps. This is different in a game such as Crysis, I see both GPUs at 100% and I get around 40 frames.
My question is, why is this? I understand the GPU under clocking to save power/temps, but I would want it to do this when I am over 60 frames.
Edit: Post was misleading. I am not comparing the frame-rates, just the GPU % usage.
