I would check the log files and see if they shed some light on this.  I 
would check dmesg, messages and Xorg.0.log as well.  The last one may 
show the best clues.  If nothing there points to anything good, I would 
post the xorg.conf and Xorg.0.log as attachments.

I have a CPU like yours except 4 core and a little GT-220 card, wimpy 
compared to yours.  What you see about the refresh rates is displayed on 
my machine too.  The last part appears because you hit the close window 
X instead of doing a ctrl c to stop glxgears.  If you start glxgears and 
do a ctrl c to stop it, the last part won't be there.   I mention this 
because that *may* have nothing to do with the problem you are having.  
This is what happens when I run glxgears:

fireball ~ # glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
27770 frames in 5.0 seconds = 5553.918 FPS
9783 frames in 5.0 seconds = 1955.847 FPS
3084 frames in 5.0 seconds = 616.716 FPS
3085 frames in 5.0 seconds = 616.942 FPS
3105 frames in 5.0 seconds = 620.981 FPS
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server 
":0.0"
       after 42 requests (42 known processed) with 0 events remaining.
fireball ~ # glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
14932 frames in 5.0 seconds = 2985.639 FPS
3011 frames in 5.0 seconds = 602.125 FPS
^C
fireball ~ #

The last one was stopped with a ctrl c as you can see.  The first was 
closed by hitting the close window button.

If this doesn't help, at least you know to post the files so we can look 
them over.  Maybe someone will notice something out of place.
