Hey guys, I'm pretty confused on which sound card to go with. I will be using optical to my Sony HT system, but I'll also be using Audiotechnica ATH-A700 headphones a lot. I am a gamer so positional audio is important to me, but my PC is also going to be an HTPC for music and movies, so quality sound is also very important. I really want the DDL/DTS:Connect feature for games, since I don't need EAX (although it would be nice). What is your advice?
