Forgive me if im mistaken but i dont believe there are any pc games that support dolby digital and dts formats. When will pc games start utilizing this? I think surround sound like 5.1 and 7.1 are a big part of gaming these days with consoles like 360 and ps3 supporting them, it makes gaming that much better. I cant count how many times my onkyo 7.1 system has saved me from being snuck up behind by an enemy locust in gears of war and being blown to bits by their shotgun. And IF pc games do start coming out with dolby digital, will you need a standalone sound card to process it to a home theater receiver or would onboard sound with digital optical out suffice?
