You can't use your video card and the video-out on the motherboard, it's either-or.

Your video card probably has 1 VGA, an s-video, and 1 DVI out. Plug one monitor in the VGA and the other in the DVI, simple. Make sure you have latest drivers from nvidia.

You can! Well, I can anyway. It might depend on the chipset though. I have a computer with onboard graphics, to which I added a dedicated card.

The dedicated card had one VGA Out, and the Onboard had one VGA out. I could use both VGA Out's for dual screen action!

It really depends on the board. You might be able to find a setting the bios to enable them to both be on. Without knowing which board you have it is difficult to say though.
