That page says:-
Dual VGA Output
The interface of this motherboard supports dual VGA output both HDMI/DVI
and RGB and is HDCP compliant allowing playback of HD DVD, Blu-ray Disc.
That suggests to me that you can use both at the same time but I must
admit it's ambiguous.

I'm pretty certain that to have two monitors (know as double headed) you
need a graphics card that has two outputs, a separate graphics card
won't 'play nicely' with the built-in graphics.
