Ofcourse the 3-Sli would kill the 6990, even 2x sli would. But i honestly dont think its worth it going tri sli with those things. If your planning on Sli Gtx580 setup, might wanna wait and see what the Asus Mars 2 video card has to offer first, its basicaly what the gtx590 should have been, true dual gtx580's. But if you really wanna sli also check out the new Asus Matrix Gtx580's, They have Direct CU II cooling and 19phases Vrm, they overclock higher than any other gtx580, they look sweet too, but the prices might not be so sweet lol.

Thats not really fair because a single gtx590 is much slower than 2x Sli GTX580's, This is because the 590 is crazy downclocked and there isnt much headroom to overclock it, just a dissapointment in my opinion.
They should put up 2x Asus MARS 2 video cards against 6990 quadfire, now that would be a fair match because Asus MARS 2 is a proper dual GTX580 card, not downclocked. And If they use 19phase Vrm with those cards, there is gonna be alot of headroom for overclocking, if thats the case then i think itl easily overpower a 6990 quadfire.

If you read most of it, you'll find a theme. The 1.5GB of ram per GPU is not enough for that setup. As a result, the Nvidia solution had tons of problems with erratic FPS, and required them to turn down the settings to prevent that issue.
So, you if you really want the Nvidia setup, and plan to go 2d surround, get the 3GB 580's.

Does 3sli 3gb 580 setup outperform quad 6990?

Neither. There isn't a CPU in the world that will be able to keep up. It's a complete waste of money.Single 590 or 6990, yes. Even SLI 580's, still OK. Even so, you would need an i7-980X to make it worthwhile.
You are not considering extreme resolutions or eyefinity/2d surround setups.

As others have asked... what is the current set up?? What size resolution/how many monitors are you using?
I don't think Herr_Koos is entirely right to say you need a super CPU to run a crazy GPU set up like this. Running 3 2560x1600 monitors for gaming would not be CPU limited lol. And honestly, unless that's the resolution you're going for, either of these options are pretty much a dumb waste of money.
2 SLI 580 3gb should push max detail on anything short of the aformentioned resolution... crossfire 6990s isn't really that good because scaling is drastically reduced from 2 to 3 GPUs, and further reduced going up to 4. I would recommend, if you absolutely have to spend a couple thousand on GPUs, the 3 580s.

tnx
cpu - i7 2600k
single 1600p monitor
Reason – I want to enjoy full AA in most gpu-hungry games with minimum fps >60
you'd say it's a waste, but I can't stand when fps drops below 60, it irritates me.

i'd say get 2x GTX 580 3GB, should max out anything with full AA/AF.
check out the MSI GTX 580 Lightning XE, i think its the best GTX 580 http://www.guru3d.com/article/msi-geforce-gtx-580-light...

The only "point" to having the i7 980x/990X is for the X58 chipset... The CPU itself isn't very important compared to an OCed 960, and it's worse than 2600. And anyway, X58 isn't even much better than some P67/Z68 boards. I understand that the idea is X58 has 32 PCIe lanes but that point is completely moot with NF200 motherboards that run 4x PCIe 16 slots at 8x/8x/8x/8x just like X58 does.
