I have a gtx 760, and an AMD fx 8350 8-core CPU. I also have a cooler Master Hyper 212 EVO CPU cooler. Up to how many ghz will I be able to overclock it while not going in the "overheat zone"? And will it make a difference in my games? I play skyrim on ultra at 1080p (8GB Ram, gtx 760). Will overclocking the CPU make a difference?
