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.
