Doom 3 BFG Edtion - Nvidia Surround - GTX 670 3-Way SLI:

This game is a classic! In the BFG Edition, you can see slightly upgraded graphics and native widescreen and Nvidia Surround support. There's also some really cool mods out there for this game to make it look even better. I mean, really, what more can I say? Dave Hester, help me out here!
