OK so i had an HT Omega Striker in my main rig connected to AV40's, which sounded good. I just moved it to my HTPC and only now do i see how shitty on board sound really is. I dont want to spend a lot of money and was just wondering if there was a card i could get that would make my AV40's sound good again. I was thinking about the Xonar DG, but it had mixed reviews.
