I was lucky enough to snag an Nvidia 680 (ships soon) to replace the 6970 that powers my 3 monitor rig. I'm going to use the 6970 to replace 2 5850s in Crossfire in another rig. Also I have a rig running 2 460 GTX-768s in SLI. I think the 5850s might be faster than the 460s but they might return more $$ than selling the 460s. The rigs are in my configuration. Your thoughts? Sell the 5850s or 460s?
