Run supersampling at its highest and Ambient occlusion at its highest through nvidia inspector(not the inferior control panel) and watch your 680 crawl.
Infact running supersampling on a game like metro or even crysis(YES CRYSIS) on 4x4,8SQ or 32x will bring a good 680 right down on the fps,more memory is better if you plan to use these features.
Ive said this before in this thread but some people seem to be ignoring it,2GB is not enough if you go down this route.
If you dont plan to use these features then i suggest you go buy a console and sell your pc.
I'm sorry but what? Not everyone can afford to spend stupid amounts of money on a pc you know. The last part of your post is just... I don't even know how to describe it. I don't run every game on ultra with my 580, yet I'm not going to sell my pc for a console just because of that.
People just seem to want to make ridiculously controversial posts for attention it seems recently...
