Asus P5B-Deluxe vs. DFI Infinity P965-S

Trying to decide between these two boards. Among other things, I'm wondering how the onboard audio between the two compare. Significant difference?

Audio Chipsets:

P5B has: ADI AD1988B
Infinity has: Realtek ALC882 High Definition

Any other input regarding this board comparison is welcome.

I've had both a 965-S and a P5B-E. Far as I can tell, the audio sounds about the same on both but I cannot get the rear speakers to work on the 965-S. In all honesty, I really haven't had time to check whether it's the driver on the DFI or if something is wrong with my speaker cable. Sound is not a big thing for me.

Yea maybe this should have been in the sound forum.. If not that much of a difference, that's good. Now I'm looking at the Abit Quad GT, oh that decisions!
