again if you get 1 Video card the 3rd had to be a Display Port. What you would have to do is a get a video card, will probably have 2 DVI and then either a DP and HDMI on the high end cards. Then you have to buy an Active Display Port to DVI adapter and also a DVI to VGA Adapter if you need 2 DVI's and 1 VGA. Right now I don't have time to go searching for video cards but you'd be better off with an AMD video card since they have supported more than 2 monitors on 1 card longer than Nvidia have.
