I just checked the ATI site and that's a gaming chip.
Found here:

That seems like a very good card.
Only question I have is about this:
Operating-System - Windows XP Media Centre Edition
I'm not sure whether that's much different from the home edition, shouldn't be a problem though, have fun :)
Oh btw if you're gonna buy that, get the Norton Antivirus half price thing too, it's worth it :)
