EAX and 5.1 support? other questions.

I just custom ordered my first gaming PC. My motherboard is a GigaByte GA-X58A-UD3R (it has 7.1 Dolby audio)

This is really a two part question:

First: one of the games I ordered lists Sound device, EAX, and DYNAMIC MUSIC in the audio options. what do these options mean and which one would I choose to support a 7.1 headset/ 5.1 surround sound system?

Second: I am looking to buy the logitech Z-5500 5.1 audio system. What cables do I need for this to plug into my mother board?

Here is a link to my motherboard that shows the inputs on the back, just click on the small thumbnail below the main picture http://gigabyte.com/products/product-page.aspx?pid=3449#ov

Here is a link to the surround system. Just click on specifications and it says what cable it comes with.

I am sorry if I placed this thread in the wrong location, but since it was dealing with videogame audio I thought it was the best spot.

    1: EAX is an old audio spec that allowed for extra environmental effects when paired with an EAX capable soundcard. Its more or less a dead spec at this point. EAX 1-2 are supported by most chipset vendors, and 3-5 are supported only officially by Creative soundcards using the X-fi chipset. If you have the necessary hardware/software support, then go with EAX, but its not a dealbreaker.

    2: For the Z-5500, you have two options: Analog or Digital. Analog typically offers higher quality, so you would plug the color coded analog audio outputs from the motherboard to the Z-5500 (There should be 3 outputs, Green and two other colors I can't recall right now :P ). Digital is only one wire and offers the advantage of passing through all Dolby/DTS audio tracks to the Z-5500 to decode (which lessens the workload on the PC when those types of audio tracks need to be played back), but offers slightly less audio quality.
  2. Thank you. this means so much more sense to me now. Can't wait to enjoy New Vegas in surround sound!
