DG965WH motherboard - 3 monitors?

[Solo]

I'm currently running two monitors off of a Nvidia graphics card with 2 DVI ports. I have a third monitor that I'd like to use as well (VGA) and thought I might be able to attach it to the motherboard VGA port, but it appears that can't be active at the same time as my graphics card. Is there any way to use that port at the same time as the graphics card is in use?
