When I had two GTX 570's, I was able to max out all of my games at 1920x1200 resolution and still maintain around 60 fps (if not higher). This included the heavy hitters like Crysis, Metro 2033, and GTA4.
As num1son mentioned, if you're going to be going for a higher resolution (ie. Surround), then the GTX 580's with 3GB will provide the extra oomph to run that. If you're keeping the same monitor, you'd be hard pressed to find much more of a performance difference with a third 570, let alone switching to 580's, in which case, you may as well stick with what you have (unless you are into benchmarking or folding).
