Hey all, I would like to learn how to overclock my gpu. the gtx 770 I have now is a reference mode with 2GB. It runs and 80 degrees right now when I use unigine heaven benchmark at ultra 1920x1080 and i would love to get some more performance out of it. i know you need some software like msi afterburner but i don't know if i need the card to be made by the same company as the software, heck I don't even know who built the reference card since it came with a pc i brought before. what temps are safe and how far can I push it.
