For comparison:

6799 frames in 5.0 seconds = 1359.743 FPS
6961 frames in 5.0 seconds = 1392.055 FPS
7015 frames in 5.0 seconds = 1402.842 FPS
6660 frames in 5.0 seconds = 1331.944 FPS
7034 frames in 5.0 seconds = 1406.609 FPS
6960 frames in 5.0 seconds = 1391.793 FPS

That's on an Intel mobo with a 2GHz Core 2 Duo and 4GB of RAM, using the
*onboard* 82Q963/Q965 graphics chip. So either glxgears isn't a very
representative benchmark, or installing one of these graphics cards is a
waste of time. I'm not sure which.
Or it's badly setup, because my low-end NVidia Cards beat that easily. (I have a pair of Quadro NVS 290 PCIe 64MB - admittedly using genuine NVidia drivers)

[sam sam ~]$ glxgears
9648 frames in 5.0 seconds = 1929.527 FPS
9566 frames in 5.0 seconds = 1913.107 FPS
9679 frames in 5.0 seconds = 1935.721 FPS
9621 frames in 5.0 seconds = 1924.059 FPS

FWIW, I see a definite difference between the card running 2 x 1280x1024 monitors vs. the card running 1920x1200 + 1280x1024 - the latter consistently scores in the 1700-1800s, the former (above) scores in the 1900s. Each card is running NVidia's TwinView, but I don't have Xinerama running to bind the two sets of screens together.

(note to others - don't try running Compiz on this setup, it really really can't handle a 5760 x 1200 array of pixels yet)
