Well, I'm glad I tried it before I read that page.  According to
Wikipedia the 7900 GTX (theoretical) fillrate is 10.4 Gigapixel/s.  This
seems like more than enough to handle what I've got running.  The card
is generating two 3840x1024(60Hz) screens and it is a 7900 GTX.  Could
the 2560x1600 limit be due to operating system limitations?  My setup is
running on Linux (64-bit) with the 1.0-8762 nvidia drivers.  It would be
interesting to see if this same configuration can be implemented on a
windows box.
