I have a Radeon VE which has dual displays but one of them is RGB and the other is DVI.

I used the dual displays in XP and it is great. It allows you to basically have multiple desktops... I can have a word document open while browsing the web or have 2 web pages open for increased browsing power on the internet (especially the Empeg Forum!!).

I also use 2 monitors to do my web page editing so that I can view updates on one monitor while editing it on the second.
