Apple Cinema Display, can I connect it to my computer?

Hi, I have an HP Pavilion with VGA output and I've been seeing so many Apple Cinema Displays on good prices I'm feeling tempted to buy one, but I'd like to know if it will require a different video card, Since it says it has only DVI, Firewire and USB 2.0 support.

The reason I want this display is for sharing it with my computer and my XBOX 360, and if it does not support VGA then a 360 VGA adapter won't work for me.
