If you use certain drivers then it may well work. I run that setup with no problems, whereas others have changed their sound card.
If you don't want the front bay then get the Xonar - it's supposed to be a better card.
Well gaming means a X-Fi card either CL own or rebranded Asus etc. As for music then there's M-Audio/Emu etc but those have no hardware D3D mixing or hardware later EAX, usually EAX2 in software. M-Audio seem to be a bit rubbish with driver updates as well. Any that release at least bi-monthly?
Works fine for me, but then I was under the impression the 'cheapest' X-Fi wasn't a 'real' X-Fi
