I have had my x-fi xtremegamer for quite a while now, and it has worked with no issues. However I want a new card that is capable of decoding 5.1 (such as plugging an xbox 360/ps3 into it). However I am having trouble finding one that can do such a thing, usually the ones I find can encode 5.1 but only decode 2.1. Any suggestions? Preferably under $100? Also needs to be able to hook 5.1 up to it via analog inputs.
