The 2G is the newest card on the market right now thats based on the C-Media line of chipsets [ASUS and HT Omega], as opposed to the X-fi chipset [Creative]. One of the highest quality cards out there right now, while still supporting all the features that digital users would need. The only thing it doesn't have is a dedicated 6.3mm headphone amp...
As for the X-fi being "gaming oriented", its called "Marketing". Once upon a time, when EAX was the audio standard, all audio was hardware accelerated, and when we all used Pentium 4's, yes, the X-fi was clearly superior for gaming. Now, its basically an aged chipset thats outperformed by newer parts. The only X-fi based chipsets I can recommend at this point are the Auzentech Forte and Titanium HD, both of which are geared more toward dedicated headphone users, and thus a different product then what you need.
The only thing to note is that when not using an X-fi chipset, you lose EAX 3-5 support. Not that many games use EAX anymore, but there are some people which would argue that a few extra effects outweigh better all around audio quality.
[And yes, I'm still working on my long promised audio guide; I might actually get my soundcard guides done first at this rate...]
