Still using a PCI XtremeGamer. The onboard sound on my ancient P965 board is atrocious though. Even with new motherboards. I would expect the DAC to be awful and prone to interference from other mobo components, so unless you are outputting a digital signal over SPDIF to be decoded on a receiver, I would stick with the sound card. I output to Sennheiser headphones (no amp) and analog speakers.
