ASUS Supreme FX II

Hi guys.
I got Asus Supreme FX II sound card to install to Gigabyte-890GPA-UD3H motherboard.
Question No.1: Would this two devices work together or Asus sound card only for Asus motherboards?
Question No.2: Where to find drivers for sound card?
Thanks (d)

Stick to the Realtek onboard you have. Those Supreme FX cards aren't really sound cards, they are more like an audio riser card as the motherboards that come with them have no audio built in/on the motherboard.

As far as it working on a motherboard other than the one it came with, I honestly have no idea as I have never looked into it. If you do want to try it then you will have to find one out which of the Asus boards it came with and then get the ADI/Soundmax driver directly from Asus.
