Crossfire vs SLI Performance Comparison Review

Testing:

Warhammer 40,000: Dawn of War II is a Real Time Strategy game that is significantly different than its predecessor, with improved AI and an improved physics engine. You can play either as a single player in campaign mode, or in a multiplayer game where Microsoft's Live ranking system can be used.

Higher Scores = Better Performance

In Dawn of War II, the quad GPU champ is the GTX 295 combo at 1920x1200 and 2560x1600. The GTX 285, however, is beaten soundly by the HD 4890 CrossFire setup at 1920x1200, while the performance draws even at 2560x1600. There is not a single setup here that results in a game that is unplayable.
