As I promised a while back, I finally ran some tests using a dual pci-e
system. Video runs fine on either pci-e card with low xorg cpu usage. But,
on a third pci card, you can clearly see the slowdown. I will try to ask
nVidia what is going on. As Jean-Daniel's pci is fine using xf86 instead of
xorg, I will try to dig up one of our old debian installs and see if this
problem is xorg specific. It may even be xorg 6.9/7 that the problem first
appeared in.
Thanks,
