Use both DVI and VGA outputs

If you have Flat panel screens, then they may have digital DVI inputs. So you can use a quite ordinary video card to drive two monitors at the same time.I have an ATI Radeon 9600 to drive two EIZO LCD panels.

After connecting the monitors, right click on the Windows desktop aera ->Properties ->Settings, click on monitor[2] then check the bottom "Extend my Windows desktop onto this monitor"
