I have a n760 tf 2 gb gpu and when i oc it there are no changes in fps.I have a amd cpu ie fx 6300 and a 650 watt corsair psu and i also have a 8*1 gb kingston ram.I dont think that my processor or the psu would bottleneck the gpu performance.I play bf 4 and crysis 3 on ultra at 1080 p but still when i oc my gpy there's no change in the smoothness of the game.SO any idea whats going on.I would really appreciate your help guys.
