if you're using win95 and above you can use two graphics (one PCI and one AGP) I ordered an ATI Radeon PCI for my second card for it's hardware decoding and visual quality. Right now I have a cheapy Trident card as my second, but my first is a GeForce2 GTS 64MB AGP. If you do this just make sure to set primary VGA in your BIOS to PCI otherwise Windows wont see the PCI card. I like dual cards better cause it allows you to maximize windows on each monitor while dual head displays usually only maximize through both and it just doesn't look right especially if you've got 2 different monitors. But bewarned that if you use two different cards certain programs like the DVD player some games and professional apps will only work on one monitor.
