here's what you want
1) 2 monitors
2) and and adapter that supports two monitors or get another PCI card

if one of your monitors is DVI,, (since you seem to have a card that supports it)... you can go ahead and use dual monitors,
if you have 2 lcd's then you need to get a DVI to VGA adaptor.
or if both your monitors are normal VGA.. then you need to get a VGA to DVI adaptor... you dont need to be einstein to figure that out..

hope it helps ..
