Been running one for weeks... onboard audio and NIC work perfectly. I used to use a Creative Sound blaster live, and a Netgear NIC, but, the on board stuff works as well for sure. Very high quality output.
Stable board, VERY fast, lots of extra's... certainly a good board to get, I would probably get the Asus or wait for the Abit now... but, I couldn't wait, and I have been very impressed with the board.
