Re: Is my CPU holding back my GPU?
It depends on your monitor's resolution. At low res such as 1280x1024, the CPU will almost always be the bottleneck with a high end GPU. At higher resolutions, there is more stress on the GPU and it becomes the bottleneck.
You could always just overclock your CPU, if your FPS rises, then it's bottlenecking.
