How to Use 3 Monitors

The motherboard that I'm using is an AsusTek M3A (details here) and the video card I have is an ATI radeon 3870. The problem is that the video card only has two DVI slots. What would be the easiest way to get triple monitors going? I could install another video card but the motherboard only has one PCI express x16 slot (which is used by the ATI card). Would an old PCI 2.2 video card work?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

The BIOS on my motherboard still gives an option to initialize the PEG (PCI Express Graphics) or PCI slot first, so I would assume a PCI 2.2 card should work.

If it doesn't work, you could certainly use a USB-to-DVI or USB-to-VGA adapter.

I do remember running into compatibility issues with some really old PCI video cards in a multi-monitor setup back when AGP was all the rage, but if you already have a card it wouldn't hurt to try.
