I have a pre overclocked evga 780 that works great with its factory overclock but when I overclock it a little more it will crash but only when I am playing a game. All of my stress testing programs (furmark heaven and valley) pass with flying colors but its always a no go when I play any game. The game will just freeze and not recover except for one or two instances in batman arkham asylum. I just want some advice as to why this is happening?
