The above advice is wrong. I run 3x 30 inch monitors, it's roughly the same bandwidth that you'll be running. The issue is, in surround and especially 3D, tri SLI doesn't scale nearly as well as it does in normal circumstances.
I have played a ton with both gtx480 sli and tri sli. There is only a small difference between them. TBH, the limiting factor is frame buffer (VRam) and texture units.
I would get 2x gtx580s. DO NOT GET 570s or 470s, at that res you need all the TMUs and memory bandwidth you can get. The normal rules of scaling don't apply the same way.
So yea.... get 2x gtx580 and be happy.
