Right video card for the job...

My first post woot!

Anyways I'm shooting to make a media center computer. The whole box with all the goodies video card, hard drive all the good stuff. What I'm trying to find is a decent video card that supports HDMI that will work well on my HD LCD. I have a Panasonic 32 inch LCD model 32PFL5332D. I plan to buy a much bigger and nicer TV later but for now this will do me fine. But back to what I'm looking for. I'm trying to find a video card that supports HDMI without a problem. Now I'm not fully sure if this can be done or not but can sound be streamed over the video cards HDMI port? If so great if not well damn thats kind of a wall for me. Anyways thanks for the help hope to hear from someone soon. Oh and I wanna try and keep it in a decent price range.
