So I just got a new Media center Pc. I'm planing on buying a video card and sound card. Right now I don't have a hi-def TV but I will be purchasing one shortly and I'd like HDMI. First will DVI-HDMI look like as good as HDMI or should I buy a true HDMI out video card? Next how do I get the audio into the HDMI cable from the video card to TV? Would I have to buy a new tuner card to get High def out of my pc? Like an HDMI in?
