Decent Graphics card / 64 bit system / imaging

[Labitt, Bruce]

I'm upgrading the graphics card on my 64 bit desktop system (Scientific
Linux 5.1 x86_64).  I'd like to use VTK to visualize some of my results.
I only have the built in Intel stuff on my mobo (Optiplex 745, 8GB RAM).
Can anyone suggest a decent graphics card for this?  Just some Nvidia
variant?  I think the graphics slot is PCI-Express-16.  It looks like a
GeForce 8800GTS SSC would be ok.  I need two DVI ports.  Comments?
