So I seem to be having a CPU bottleneck with my current PC but I'm slightly shocked that the CPU is the bottleneck. I'm runnin an i7 930 @ 4.2 GHz and a GTX 480 that is overclocked as well. I can bounce the GPU from 600mHz to 900mHz and I'm not gaining any perfomance out of the overclock so that tells me the CPU is holding it back. My display is a 1920X1080 so it should be big enough to allow the 480 to stretch it's legs. Any thoughts on this?
