If you are building or upgrading your existing system the Matrox P690 is an excellent choice. Ultra low power consumption, passive cooling - no fan, no noise. Very relieble and Matrox has excellent multimonitor desktop management software.
In digital mode each card can drive two monitors each up to 1920 x 1200, in analong mode two monitors each up to 2048 x 1536
I'm selling two of them on ebay, Retail versions with original box and two VGA adapters.
