Hello. I would like to know what is the best, stable overclock I can get on my graphics card using MSI Afterburner. Here are my specs: http://pcpartpicker.com/p/2HxMkL . I have dabbled into a bit of overclocking however it seems to either be unstable or not fulfill my needs. Basically, I want an overclock that can keep 60FPS in GTA V at very high settings at all times. Base clock will keep 60FPS most the time, but there are dips into the mid 50's when doing anything really intense in the game.
