What is the difference between 1x, 2x, 4x, etc, if not performance?  I guess 
I assumed it would be that.

No, I didn't know about that Option when I changed the BIOS value.  I set it 
now, though, and it actually decreased my x11perf score by 6 (didn't affect 
glxgears).  And I tried 4x mode with and without it; it hangs either way.

Hmm, yes.  Didn't affect glxgears, but x11perf increased by 20.
