I'm using a Gigabyte GTX 580 3GB at stock 772MHz, I want to overclock it higher for gaming purposes. At stock (772MHz,1050mV), ambient is 39C, and 60C while gaming (Skyrim, BF3, Mass Effect 3, etc.). I'd like to overclock it higher, any approximation on how much voltage i should try for 900MHz, 1000MHz and 1100MHz? Thanks.
