The MIO card does have one advantage -- it doesn't consume a PCIe slot.
 Slots 1 and 2 are mutually exclusive (the PCIe lanes are switched
between them by hardware depending on slot population), so if your
system is already fully loaded with PCIe cards and you really need audio
the MIO card can be a decent option.

FWIW, the MIO card attaches to the integrated audio device of the SP5100
and simply provides the audio codec needed to interface with the analog
domain.  Sound quality issues may also be coming from the SP5100, not
just the Realtek codec itself.
