What you have listed there seems pretty good. I don't remember the Stereo-Link, but the Extigy is supposed to be a prettyy good audio solution. I've wondered how well a digital connection would work in this setup. I was going to be building my own PC this winter sometime and will most likely use an Audigy 2 card. I wouldn't be able to hook it up to my home theater anytime soon, but was planning to use the optical digital out for this when I get the chance.

Is this the primary audio setup for your computer or is your computer close enough to your HT that it's fun/convenient to have the connection? What is a converence PC? Is that where the computer is specificly for storage pf things like movies and music, it's not really meant for gaming or everyday use?
