Yes, your card will support dual monitors. One monitor must, of course, be VGA. The monitor connected to the DVI port can either use a DVI cable or a VGA cable indirectly connected to the DVI port by using a DVI-to-VGA adapter between the computer and the monitor cable.
Note: your card may not support monitors with very high resolutions, such as 1980 x 1200 but anything lower should work.
