in terms of FPS, how much would you say it increases performance? I have heard about only 5 FPS which in my opinion doesn't seem worth all the extra stress on the video card. Just looking to see what the consensus is.
depends on how much the overclock is. if its 100mhz on the gpu 100mhz on the ram, the difference isn't very high. if you can get an extra 200 mhz out of the gpu, shaders, and ram then the difference gets much bigger.
now if your overclocking that 8800GTS 640 in your sig, you won't be able to overclock it enough to see a huge difference.
I have 460M SLI in my laptop, oc'd from stock 675Mhz to around 800. I am sure I can oc more if I want to, but I'm too lazy
Also oc'd memory, but I'm new to oc and not sure about the limit of VRAM oc. Currently I just have a small oc from 1250 to around 1400.
