Hello Fred, Chris, and AG-Tech,

Have you heard of anyone successfully using two NVIDIA multi-monitor cards
such as GeForce 6600GT 128MB DDR3 PCI-Express or NVIDIA Quadro NVS 400
Graphics Cards?  On the other hand, are there any recommendations besides
Matrox video cards for requirements of a three video card connection, two
projectors(PCI)/one control monitor(AGP)running under FC4 or WinXP node?

Thank you very much for all your help,

John Langkals

we have a couple nodes using Xentera GT 4 cards on Windows.  they work.
but we have had a problem with the VICs chewing up more than their fair
share of the processors.  whether this symptom is directly related to
the Xentera, as we suspect, since we have another identical node using
multiple display cards,
two Matrox G200 Muti-Monitor
one NVIDIA Qaudro FX 500
which handles itself quite well,
we haven't ascertained for sure.  we haven't tested swapping out the
Xenteras for a couple of important reasons.  and the problem on those
systems has not been a priority as of yet.
