Is Two GTX 770 in SLI better than HD7990?

[Mr_Noobie]

Thinking about dropping another GTX 770 into my PC but with the recent price cut of HD7990, $610 after rebate with 8 free games, I'm rethinking my options. So my question is, should I go with 2 gtx 770s or hd7990?

SLI 770s all the way, if you're looking for sheer performance. 7990 isn't bad at all, but SLI 770s will beat it and for much less, in your case.
