Matt you may as well give up, you could be getting double the fps of a 680 and people would still claim the 680 is smoother. I've tried both and they felt as smooth as each other apart from games where the 7970 gets noticeably better fps than the 680, then the 7970 felt better, 144hz monitor I'm using. My opinion doesn't matter though, those 3 guys said nvidia is better so it's better right?
