onboard and things like the DG will only send dual channel audio over the digital connection (unless the source media is already encoded for dolby/DTS 5.1/7.1) meaning you are only getting Dolby pro logic sound from the surround sound system defeating the point of a surround sound system.
where by using a card that can encode as DTS interactive or Dolby Live, it can take all 6/8 channels in real time and encode them as Dobly/DTS so when the box decodes it you are giving it instructions for every channel assuming the game supports 6/8 channel sound. so basically you get the full use out of the surround sound system.
it's basically the same as comparing connecting a stereo analog signal to a surround sound system, then connecting the 3 or 4 connections from a 5.1/7.1 sound card/chip to a surround sound set of speakers.
actually been using a Xonar D2X for a few years now because of this, since my surround sound system is one designed around TV's and stuff instead of PC's, so it doesn't have the 6 channel direct connection, so I need the signal encoded going to it to get all 6 channels of sound.
