I would not recommend this purchase for what you are attempting, as the 6600 GT is not HDCP-compliant, and therefore may not be compatible with your tv (at 720/1080 resolutions).

This card is 40$ on sale atm at MemEx, and is 100% HDCP compliant, and will even offer HDTV acceleration options that the 6000 series does not even come close to having.

Also, this model has a built in HDMI port, as well as the DVI.
