Okay hey guys.So I currently have 1 680 FTW Le 4gb version.It runs absolutely perfect ultra on everything at 1080p.I have decided to get 3 monitors so I can increase productivity and work.I am also thinking of doing a little bit of surround gaming.People say they can run 2 780s factory and have everything ultra and run 60 fps +.Should I buy another 680 for 400$ then over clock them or should I wait till the 800 series.Thanks
