I need some advise on a projector for my PC Room. It will only be used for my PC, gaming and internet browsing. The room is 11.5ft wide and I think I want to go 1080p. I dont think 720P would be high enough resolution for gaming on a large screen, I am hoping for at least 80 inches if not closer to 100 inches. I am new to projectors, so I am looking for any advise on mounting and the unit itself. I saw the thread on the Optoma HD20 that is coming out, that seems like a good bet since I dont want to spend 2K.
