Question about hardware compatibility

[xXToYeDXx]

First my hardware specs:

Chassis: Silverstone RV03 Raven 3
Mobo: Asus Rampage 3 Black
CPU: i7 960 OC to 4GHz
CPU Cooling: Corsair H80
RAM: 8GB Mushkin Enhanced DDR3-2000 CL7
Sound card: Asus Xonar Xense
GPU: 2x Asus ENGTX580 DCII in SLI
PSU: Enermax SGalaxy EVO 1250W
SSD: Corsair Force 3 240GB
HDD: Western Digital 750GB for storage

I'm aware that the ALSA driver doesn't support the Xonar Xense, but I wanted to ask if it supports the Xonar chip on the bundled Thunderbolt card that came with my motherboard. I'm not 100% certain what xonar chip the card uses, but I know it isn't the xense chip. Has anyone gotten this card to work under linux? I want to get as far away from Winblows as I can, and I'm willing to swap out the Xense for the Thunderbolt and sell the Xense + Headset. Also, and this isn't important but I still would like to know, would the card's Killer NIC chip work under linux as well.

I have googled for weeks, on and off, and I can't find anything. I'm getting desperate to get away from anything microsoft.

The easiest way to check is to try it; boot a Live CD or Live USB and see what works and what doesn't.
