Get some speakers. The CT5880 isn't at all a bad sound chip, pretty clean output signal comes for free. It's hardware sound and also supports 4 speakers.
Good speakers will make the difference, poor speakers are garbage even on the best sound card.
Another thing, make sure you disable AC97 audio in the bios, the CT5880 doesn't need the software codec and I was having some problems with it enabled.
Hope this helps
