Well since I install Dual Flatpannels for a top Financial Info Company for a living.. Two monitora have been supported all the way back to Win95 using Appian Cards like the J2N.. I actually have installed some Quad based systems using the Matrox MMS.. You can get dual card as cheep as the ATI All-In-wonders.. You can also put dual video cards in the same PC... if you want to do Dual Monitors I would recommend the Matrox G550 or the MSI 5600 with dual Video outputs.. I have the MSI now and it has 256 Ram on it also..
