[AG-TECH]Video cards

[Peter DeSantis]

For my 2c worth, we found the nvidia quadro nvs400 to be stable but massively underpowered for refresh and quality display in a multiscreen enviroment. I doubt we would ever use this card again, but it is stable and does "work"

We replaced with a matrox pci express 4 way card and saw big improvment (aside from some driver issues quirks)
