But the correct answer depends. What monitor do I have in your hypothetical?
Or are we going with what we already have?
I already have two 680's. So technically, the correct answer for me is to keep the 680, but if I had neither, and I didn't want to add a second, the answer is obviously the 7970.
If I had neither, and had the monitor I have now, then I have to say the 680 since neither the 680 or the 7970 alone are enough for 2560x1600 at settings I want, and SLI > Crossfire.
If I only have a 1080p screen, then the 7970 obviously.
You really have to give us more details so that we can answer!
