Like I have said before in this thread, I am not an audiophile and don't claim to know all the technicalities that go with it. Hell, I didn't even buy the sound card to listen to music. But both with headphones and speakers, I have definitely heard a big difference in the audio quality with a discrete sound card. And I'm talking right after installation, and then switching between the two through the playback devices option.
Or maybe the onboard sound on my mobo was mega crap to begin with. That's unlikely though as it's pretty new gen.
