The only real benefit is that you don't need a DVI-VGA converter or cable in the event you wish to use an analogue monitor. So if you don't use a CRT, or low end LCD, there is likely little use to you. This is why most recent cards are going to the 2 DVI approach. DVI-I connectors (which are what the cards use) have the analogue outs so a simple converter will do the trick, if needed.
