As the subject line suggests, what would be your preference? I want to use it for gaming as well as music, home theatre not such a big deal. Primarily will be used with headphones, and i do have a headphone amp where required (but use a headset for gaming so wont use the amp then). Anyway, the Audigy is platinum, meaning i get the I/O slot, which is pretty cool, but i presume x-fi cards are generally better (since they cost more). Prices are fairly even.
