Isn't Dead Space 2 wicked on 3 screens? I've got a little clip of my rig playing Dead Space 2 on youtube.
(Don't know why the youtube video is getting imbedded or if it is allowed. Do a channel search for "claytonjones006" and you'll find my video)
Black Ops was pretty good on 3 screens as well but I suck at multiplayer. Next time you have one of these I'm going to need to make the trip down from Ohio to meet some of you guys.
Both Dead Space games were very nicely supported on Eyefinity / Surround setups. Call of Duty Black Ops support for it was virtually unusable. Thankfully we have the Widescreen Fixer utility to resolve those issues and make the game playable.
