I think I have my computer tuned about as well as I can, with the hardware I have. I use 3DMark Demo, and 3DMark 11 for my testing numbers. I have ran 114 3DMark demo tests, and 127 3DMark 11 tests. I do a test after each hardware/software change. I am happy with the speed of my computer at this time. It clocks at 1150MHZ (1.5GHz) at a idle, but cranks up to 4845MHz (4.845GHz) when there is a heavy load applied. Pretty much all tweaks are done to the manufactures maximum specifications. It does not over heat, or give me a blue screen.
