We benchmarked the game on a 7800 GTX SLI rig, with a FX-55 processor.

In a flyby of the game, the framerate was between 90-160 frames a second, depending on the graphical intensity of the shot. The average framerate was in the 110FPS range, with the minimum framerate around 70 - it didn't drop below 60FPS once.

This was at 1600x1200, with Shader Model 2, HDR, anti-aliasing and anisotropic filtering turned on. Proof, if any more was needed, that the 7800 will handle anything you throw at it without breaking into a sweat - even next-gen game engines.

Indeed, when we switched HDR off and dropped down to Shader Model 1.1, the framerate was limited by the FX-55 processor, which couldn't go any faster.
