I bought GTX 760 anyway because the price, if I wanna go GTX 770 I would rather bought a couple of GTX 760 in SLI which I plan to do so in few weeks (GTX 770 is more expensive than a couple of GTX 760).
Specwise it's pretty tame, just barely better than HD 7850 but this card absolutely flies in games. In two of the AMD titles Crysis 3 and Tomb Raider the performance were miles better comparing maximum overclocked HD 7850 at 1200MHz core vs stock GTX 760. How come in AMD titles nvidia cards were much faster? Only downside is the reference cooler on GTX 760 sucks, in games it reaches over 80C but at least with GPU Boost 2.0 I could make temperature as a priority but still the stock heatsink is puny and can't cope with the heat the GPU develops
