Fantastic guide Nameless, answered many questions i had. I want to buy a dedicated sound card to upgrade from my onboard which uses Realtek ALC888 chipset.
I am on a limited budget and i decided between these two cards, asus xonar dg and creative x-fi xtremegamer. I know for gaming the latter would be better but i am kind worried about the performance in music. I know also that it doesn't have a build in headphone amp like the xonar dg.
After reading this review, i am kinda worried about xtremegamer's music performance

I know this review is kind of old and the card is the xtrememusic and not the xtremegamer, but as far as i know they are very similar cards, and in this review at least things aren't looking very good.
But in this review, things are way better (again xtrememusic not xtremegamer)

On the other hand the xonar dg scores very good

I plan to use logitech g51 and Superlux HD-668b headphones.
Short version: I prefer the creative xtremegamer due to better 3d audio support and cmss3d, the only thing that's holding me back is the inconsistency i see with this card in some rightmark audio analyzer results, and maybe the lack of headphone amp, although to be honest i don't know if the superlux hd668b need it. So i would like opinions about how these two compare in music and not so much about drivers and features (with the exception of the headphone amp perhaps) because i prefer the xtremegamer as i said.
