i know about the 5870. thanks for the info though. ill be getting the asus xonar 1.3 deluxe instead. its been out long enough to where the bugs have been worked out. if the asus soundcard blocks me from watching my bluray movies on my plasma hdtv then, ill be sending it back too. asus has the best soundcards out there. they put the best parts on them too, like burr brown dacs. if anyone wants 5.1 dts then stay away from the asus av100 chipsets, go with the av200.
