How much do you need to overclock a GPU to get a fairly decent FPS difference? I added 45 MHz to my default GPU clock, 30 to my memory clock, and I got 1 FPS.
Well I have been a bit more extreme with my GPU overclocking. 130MHz on core and 280MHz on memory. (Can't get more on core due to MSI Afterburner limiting the voltage increase) Really, you just have to find how high you can go without stability issues or overheating issues. (Try 10MHz increments until the game freezes every once in a while or something)
