yes it supports multiple moniters. You just connect the two moniters one on the vga and the other to the dvi(with an adapter if your moniter doesn't have the corresponding dvi connector). Then you just go to advanced tab and select extend desktop. Very easy IMO.
Dual screens are nice when you game because you can run monitering software, chat software etc on the side and then take a glimpse at it every once in a while. I want to get a pci vid card so I can trun three moniters and a psone lcd in the front of my case(just the though of being surrounded with moniters is awesome.
