Sound Card Question

[nopmike]

Hello,

I recently purchased a pair of Tritton AX 720 head phone for my xbox 360. I would like to use them with my computer too, so I need to get a sounds card because my mobo did not come with a built in optical port. What is a good, cheap sound card that has an optical out port?

This Creative Labs card is the least expensive one that I would go with ($50). It has optical in and out ports.
