The Tech Report takes a closer look at the issue by testing the latest integrated Realtek codec against a couple of sound cards: Asus' $30 Xonar DG and its considerably more expensive $280 Xense cousin. Everything from gaming performance to signal quality is explored, and it's the blind listening tests that prove most revealing. The integrated solution is obviously flawed, and in a bit of a surprise, the cheaper Xonar is the one most preferred. Discrete sound cards certainly have their benefits, and you don't need to spend a lot to get something that sounds a lot better than the average motherboard.
