Hi,
On one of my machines here I'm running an NVidia 465GTX card
driving two 1920x1080 monitors in Twinview mode which for reference
produces the following glxgears results:
Default size - Approx. 10K fps
3840 x 1080 - Approx. 1500fps
mark@c2stable ~ $ glxgears
39852 frames in 5.0 seconds = 7970.263 FPS
39793 frames in 5.0 seconds = 7958.562 FPS
48631 frames in 5.0 seconds = 9726.093 FPS
49370 frames in 5.0 seconds = 9873.878 FPS

I'd like to add a 3rd monitor, probably a 1280x1024 I have sitting
here, but the 465GTX is out of ports so I was considering buying a
cheap NVidia PCIe card to drive that monitor. The main purpose of this
3rd monitor will be nothing other than watching NetFlix/Hulu in a VM
while working on the two original monitors.
Does anyone have experience with driving 3 or more monitors using
non-identical NVidia cards? Are there any performance issues I need to
be aware of if I put a lower performance card in with the 465? If I
snag an old 8200 type card for $29 will it kill my 465's performance
in any way?
Thanks,
Mark
