Dude, Your rig is not complete without this: http://www.youtube.com/watch?v=HWm9PtzWvko

It's two projectors stitched together by a program called Warpalizer, the result as you can see is great with no seams between the two projections. Also what's good about using two projectors is that you get a tad bit lower resolution, but much better performance, I think it's going to be like 3840x1200/1080. The program can cast a correct image on a bent screen giving you at least 130degree viewing angle. I would definitely go for that rather th an 3 screens if I had that computer. I've tried it myself and it's pretty damn fantastic!
