I have been using onboard audio since an nVidia nForce 2 motherboard had issues with a Creative Labs Live! sound card some years ago. My biggest audio use has just been for playback of MP3 and games, but when I built my home theater system I thought of getting a dedicated sound card and just couldn't justify it as the sound was adequate. The Auzentech X-Plosion has changed that position, as I can clearly hear the difference between the onboard sound and the X-Plosion.
