is that what you are doing as well.?
any overclock on your 580.?
Overclocking hasn't been necessary for me yet on: Skyrim, COD: MW2, BFBC2, Fallout 3, and Rage. No issues running those games at full settings.
My strategy is to wait for the GK110 "Big Kepler" GTX 780 to be released early next year. I'm assuming they will refine the current Kepler cards and really come up with a nice product, similar to what they did with the GTX 480 to 580 leap. Until then, there's really no reason to upgrade to something that doesn't add anything in terms of gameplay image quality settings.
