Upgrading from 2 Eyefinity 6 HD 5870s

Ok, so I'm currently running two Eyefinity 6 Edition HD 5870s and they're getting a little dated. I'm ready to move them into my backup computer and go with something new.

Here's the premise - I run 3 24" monitors at 5760x1080 oftentimes, so I want to be able to smoothly run games in Eyefinity. My budget is $1000.

I'm stuck between EVGA's GTX 690 at $1000, Powercooler's 7990 at $900, and two 7970 GHz editions at about $450 each.

I want to avoid as much micro stuttering as possible, so I know the 690 is better there, but I'm worried about it because it has less memory for those larger Eyefinity resolutions.

What do you guys think?

Two hd 7970 ghz wins hands down. Better than HD 7990 and GTX 690, both are underclocked dual cards. Use Radeon Pro to decrease stuttering, but ur fps is gonna be pretty high so it won't even matter.

Two 670s with 4gb Vram, that would be my choice at least. BTW the 7990 from HIS in not underclocked.
Eyefinity is better with AMD, as I am sure you are aware of. But Keplers lower TDP, energy comsuption, and the fact that Nvidia has just better overall SLI support, faster and better drives for new big releases, I would go with said 2x gtx 670, because I trully think the 680 is not worth its price
