Looking for a great sound card

Ok so i have been looking for a good sound card for a while now.

i have been looking at the asus xonar d2x

and the creative sound blaster recon3d

The sound card is gonna be used with a logitech z-906 speaker system and a steelseries 7h headset.
Does anybody have any experience with any of these,m or have any other recommendations?
