I'm guessing #9
........ No, not love potion!
I'm guessing that it'd have to beat HD 7950. Probably 190-195 VP while the 7950 is rated at 186 VP.
It would make sense that Nvidia does not castrate the bastard sibling of GTX 680 any further than AMD castrated its own Tahiti, so that it still enjoys the same advantage over the competition that GTX 680 enjoyed over HD 7970. To castrate it any further would be a stupid move in this game!
