I'm looking to put together a really good HTPC that will be able to handle HD with ease. Don't care about games on it really but it has to be able to output DTS and or DD 5.1 through HDMI. I'm thinking the best processor right now is the i5 2500k. If I get a motherboard which has HDMI out built in will it also output 5.1 sound? Or do I need to purchase a separate video card or sound card. Absolute requirement is that 5.1 sound has to come from HDMI and not some additional second output. Thanks for any advice guys.
