I feel bad for my cards since they're not being taxed too much right now. Currently playing:
Call of Juarez DX10: 1920x1200 4xAA Full Details
Grid: 1920x1200 16xAA
Titan Quest: 1920x1200 4xAA (I really should force more through CP).
Of course, the games that really tax my SLI system are PuzzleQuest and Audiosurf
