Enemy Territory: Quake Wars
The graphically-challenging Enemy Territory: Quake Wars is smooth on the Inno3D card. Again, there's a significant positive performance difference between it and the ASUS GeForce 8800 GTS 320, which is priced at the same levels.
Adding in 2560x1600 for fun, the game is barely playable; you'd need SLI or a GeForce 8800 GTX/Ultra for a smooth gaming experience here.
