The R9 280X and the HD7970 can apparently crossfire

Why cant Nvidia do this with the 680 and the 770? I might go over to the red team.

Why would you SLI a new gpu with an old gpu? Just buy two 770's or pair two 680's.

The 770 is cheaper than the 680? So if you already have a 680 you dont need to get another 680, you can get a cheaper newer 770 instead.

Go for it. AMD has been doing that sort of thing for a quite some time. Nvidia for whatever reason chooses not to. I imagine it has to do with support and worry about extra confusion. Good enough reasons not to? That's up to you but that's the way it is.

Nvidia has been sitting pretty for quite some time now, I imagine they'll come back fairly soon with something just marginally better than AMD's best offerings. I feel like they have the ability to blow things up but are taking the tip toe approach for more profit. I mean if the 680 was originally going to be titan (which btw isn't even fully unlocked now), they have been researching the next big thing for quite some time.

So basically, what I'm saying is that you will never get too far ahead of the curve with the current ecosystem. You might as well go with team RED. I know I'm not as certain these days. I'm in no hurry to upgrade myself right now and will wait as long as possible for best results, but I in no way would recommend nvidia over amd with any sort of conviction.

awesome. I'll keep my 7970 then. I have the GHz edition, will that even matter? I assumed the GHz edition was just primed for OC'ing

I dont think it does matter

Your GHZ edition just means that its base is at 1000mhz. The original cards were clocked slower yet still had amazing headroom for overclocking. Yours is more or less the same card with its minimums boosted.

with sli at least the more powerful card will downclock to the weaker card, ie: 660 and a 660SC. So pairing a 770 with a 680 would be counter productive

They are so close that it would be just like a regular SLI setup. Not much of a negative effect really. I imagine that nvidia's drivers have more specific tweaks for different cards and that might be the main issue.

Its really the same gk-104 chip, with the same amount of cuda cores and everything
