So i have a i7-2700k cpu and its running at 4.3 at 1.3 volts. is that a safe voltage for it also it seems as though the processor is not performing as it should in games. Most games should run easily at 50+ fps with this CPU paired with 16gbs of ram and a 780gtx OC. Alot of games are having a hard time maxing out FPS on this set up. So is my CPU the issue here?
