Why not get a projector for the same price or less of a 60" inch TV and enjoy gaming on a new level? Im talking 100+ inches. Couple that with an epic HD audio system and you'll find yourself in gaming heaven.
Not everyone has the room for it. With a projector you will probably need at least a 10 ft throw and a mostly light controlled room. Granted I converted a bedroom into my office/home theater with an led projector, but I will not go back to gaming on a tv after having a home theater in my last house. My little $400 led projector does a nice 100" 720p image so i'm happy. Once the 1080p led projectors come down in price I might upgrade.
