So I just picked up my new Asus p67 Deluxe Motherboard, my i5 2500k, Coolermaster Hyper212+ and my new Antec 1200 gaming case. I would like to know how to overclock the cpu to 4.5Ghz. What I would like to know is: What settings to change, what settings to leave, and what kind of gaming improvement will I see from it.
