I'm looking to OC my Asus GTX 650 but I don't know which software I should use. My GPU runs at 54c max temp when under 100% load.
msi afterburner will be the best software in terms of ease of use.
I disagree. Precision X from EVGA is a very good and easy to use software for overclocking. includes easy Over Volting and a lot of features including FPS caps to minimize power usage in games where your GPU is overkill.
My GPU isn't overkill in many games xD I don't think I'm going to change voltage or anything although I'm just going to up the Core clock and memory clock a bit
