Best Triple surround/eyefinity games

I currently use a triple monitor set up but only play WoW. I'm looking to try something that will immerse me in the game with the crazy coolness of triple monitorness but I have no Idea which games are best for it. I'm also wondering if there are any free to play games that are cool with triple monitor since I'm broke.
Shoot.

I think Hawken has that. It is a free to play FPS mech game. It is in closed beta at the moment but it shouldn't be that hard to get into.

Cool looking game. It's a shame I have to wait a month to play. Any others?
