3 580's will be about the same as 2 6990's, but 580's are easier to find. there are also 1.5GB and 3GB versions of the 580, the 3GB one is just a gimmick and barely has any performance increase.

Hopefully this helps:

THere are 2 kinds of 580 Cards. 1.5GB and 3GB. Don't waste your money on the 3GB. Get the 1.5GB.

Nvidia ones are better.
They have much better drivers.

Get 3-way SLI.

It comes to whether you like AMD or nVidia. 3 GTX 580s will give you about the same performance as 2 of the 6990s. The 580 cards are easier to get a hold of. There 1.5GB and 3 GB versions of the 580. The performance boost you get from a 3GB version is not worth paying the extra cost to get it.


edit....Bah........beaten to the punch
