Started playing bf4 and getting 70-80 fps on ultra 2560 x 1440 res . I overclocked the gpu that gave me at least 10 fps. Now i want to know is it possible to overclock the cpu. I tried different software none work. Im running windows 8 through bootcamp. I know mac doesnt use BIOS. but is there an alternative? Im new to mac rumors i hope this isnt the wrong section.
