My MSi GTX 560 ti is getting old, I play pretty much all games with mid-to-high details (1920x1080@60fps vsync), but far from using the ultra settings. I want to upgrade, but I'm not rich enough to buy a GTX 780 (hehe). What would be the best upgrade for me here? The GTX 660 doesn't seem that much of a boost... GTX 760 would maybe do it?
