Yes, I understand the concept (although it's not apparent from my post). 
Wikipedia has a nice article on the different kinds of DVI.

Based on what I've read on a couple of gaming forums, it's not just about 
"dual link" -- I need a card with a dual-link DVI-D (DVI-I won't work). 
Although I couldn't really figure out what the difference was between the 
"D" and the "I", besides the fact that the latter also has analog pins. Does 
"D" have higher bandwidth?

The connector in my video card looks like a DVI-I (Dual Link):

By the way, the card is a GeForce 7900 GS.
