I have considered that, but the computer (at least the one I will use) and the projector are in very different parts of the house. I have a "media pc" in the room with the projector, but the comp in the office is 100 times better (Crysis on "very high").
I haven't played Crysis online yet, but often play the single player.
Returning the COD: WAW and the extra controllers I bought tomorrow. Have the game on order with a new gaming headset which should arrive in a couple of days.
