All of the scores are taken under Normal Quality settings and sound turned on. V-sync is disabled and desktop color depth is set to 16-bit (which means the demos were run under 16-bit color).

At 640x480, 800x600, and 1024x768 we realize a 17% performance increase due to overclocking. 1280x1024 shrinks the gap to 12%, but even still, the gain is more than significant considering we haven't spent any money on extra equipment!
