<< My MB has it on-board, and I like it. The Win2K driver is good (WDM, no bullshit), and it's said to have 4-speaker support (I don't have the appropriate connector though). >>
I agree there too. I have had it going in basically every OS and it hasn't flinched once. It does have excellent, easy to install drivers, and they are stable. And I have tried the 4 speaker thing, and it does work pretty good. Not as good as the SB Live! or Vortex 2, but for something onboard, its pretty good.
