  I think the resolution can change the benchmark considerably.  Try 
making glxgears full screen or very small.  My screen is 1600x1200 and 
the default gives me 2400 FPS.  I can reduce the window and get over 
6000 FPS or make it full screen and get 184 FPS.  Note that the 
eye/brain can't see more than about 24-30 FPS.
