8800GT and SPDIF?

Was wondering which of the 8800 GT 512 have the spdif loopback? I want to use a dvi-hdmi cable to my tv and have sound (one less trailing wire :D ), I've checked the specs for my soundcard (x-fi fatality) and it should have an spdif input and output but finding a graphics card that has the connection is listed is very difficult. I know Zotac should have some but checking their site I cant see anything listed against the card.

The ATI cards have audio over dvi-->hdmi but the cards cost about the same ~£20-£30 so it doesnt make much sense putting that much money up for a lesser card.

Any help is appreciated.
