Which sound to use?

[Nitemare]

I'm going to have 2 rigs, mainly for DVD's and the occasional game.

I have a Turtle Beach Santa Cruz 5.1
onboard audio for ASUS A8n SLI-Deluxe
onboard audio for a Soltek SL-K800PRO-939

The sound card could go in either one or stay out completely.

IMO, I would just use the onboard's.
