This new card announced by ATI looks to be pretty cheap and has all the makings to become a very great HTPC video card. http://feeds.engadget.com/~r/weblogsinc/engadget/~3/407510677/
Previous cards suffered because they did not allow audio via the hdmi connection *sad times* meaning that you couldn't get (or it was SUPER HARD)HD audio to a reciever in any sane way. Now... one cable and you got HD video and audio. WEEEE.
Now if we could just get some of this cable card mess sorted out I MIGHT consider ordering cable LOL.
