I was looking into 1600 monitors as well, but most of them are strangely expensive. As in not cheaper than $300. I think I'm just gonna get 3 1920x1080s and 3 GTX 680s, and sell the 30.
That would be your best bet. If you want the best graphical res, go x1600, but you want to be surrounded by awesomeness, go 3x 1080p monitors. It is much cheaper and in my opinion, a much better gaming experience.
