Nvidia 6600 HDTV Output Better than the 6800?

SupaFox asks: "I was reading through the specs of the soon to be released Nvidia GeForce 6600 and on the last line of the features and benefits page it reads: 'Integrated HDTV Encoder Provides world-class HDTV-out functionality up to and including 1920x1080i resolutions.' I don't see this listed explicitly on the features page for the potentially more expensive 6800. Does that mean using a 6600 is a better option for someone building a media center or HTPC or getting a fancy new LCD or Plasma display as a primary or secondary display option for a PC or is the 6800 just as good? Any thoughts?"
