I think I will need to upgrade to multiple monitors before I'll "need" to add another 580...(you need SLI to use surround view). By the time a lone 580 can't handle higher than average settings it will be time to get a whole new GPU. The new game releases don't really require that much GPU power these days when compared to older/existing games...though (hopefully?) that might change one of these days. Metro 2033 is pretty much the only exception and has become the new "Crysis"...however, even on high settings the game is fine.
I agree with Vagrant. Based on your needs and plans for upgrading to Kepler later on, I think a 560 Ti would actually be perfect for you (especially at 1080p).
The 1GB frame buffer shouldn't be a major bottleneck in the immediate future (certainly not before Kepler is released anyway) and the 560 Ti can handle most titles at that res comfortably. If you still want more power, there's always SLI, which would be significantly faster than a 580
for roughly the same price.
I'd grab a 560 Ti Hawk from MSI or a Direct CU2 from Asus. Aside from being great cards in their own right, those brands tend to hold their resale value a bit better because of their serial number based warranties.
