Can I connect three monitors to the Geforce GTX 480 or the Geforce GTX 470 graphics card?

The Geforce GTX 480 and the Geforce GTX 470 typical comes standard with two dual-link DVI connectors and one mini-HDMI connector. Although you can connect up to three monitors on each graphics card, only two of the monitors may be active at the same time. If you need to drive more than two displays at the same time, you will need to add a second graphics card to your PC.
