Quote from OldTrader:
"... So in the case of the T3400 it looks to me like you're right, using 2 quadro NVS 290 PCIe x16 cards would be the ticket, one that comes with the computer, and one that you would buy separately and install.
Anyone disagree with that?
No disagreement, and I believe the 290 has a manufacturer's 3-year warranty.
