[US] EVGA B-Stock (Refurb w/1yr Warranty): GTX780 Superclocked ACX (129.99$), GTX780Ti Kingpin (199.99$).
The GTX780 at 130$ is a lot of card (~RX470/RX570 in performance) for relatively cheap, if you don't mind the higher power consumption. The Kingpin GTX780Ti is the fastest GTX780Ti ever built, with a 23% OC from the factory. That puts it into the R9 Fury/GTX980 range of cards, if you don't mind the (crazy) 2x-8pin + 1x6pin power connector requirement.
