I am looking to upgrade the sound card in my HTPC. It must have a optical out on it to connect to my receiver, and it must have Dolby Digital and DTS decoding built in. I Won't be using it for recording anything or doing any gaming so maximum DVD/media file playback quality is desired. A Would prefer to keep the cost down. I looked at the Turtle Beach CATALINA 8 but the reviews on the web were not that good.
