I've read that one problem with motherboard audio is "digital noise" 
pickup due to exposure of the unshielded circuit to various waveforms on 
the motherboard. On laptops I've measured noise levels on the headphone 
output as high as -30dB.

So much so that the ASUS folks make a high-end (consumer) PCI-Express card called the Xonar Essence STX, which is built around a C-Media chip. It depends on the PC's CPU to handle the processing, but that's only if you want to use the cartoony features (voice changer, "environmental" ambience and reverb, etc). As a straight-ahead sound card, its pretty good.
