If, however, you use that card to play games or watch DVDs with, you'd be wasting your money with that card, as all audio from those sources (remember, there are no DVD players which support ASIO or Kernel Streaming) must go through the WDM drivers, which (as I said) are capped at 16/48.
You would still be taking advantage of the analog section of the card, which I assume would be a huge improvement over the Audigy series (with the obvious limitation of only having 2 channels, though). And I would also assume that the DACs would be an improvement, even at 16/48, and even though Audigy has pretty good DACs.
How much of the Audigy 1/2's processing capabilities come from this chip? And how many of those do the E-Mu drivers actually recognize? It's an interesting line of thought, but it probably leads to a dead end.
