I have the ASUS Rampage III Black Edition with the Thunderbolt Sound/NIC card. I have recently upgraded to Windows 8 and I cannot seem to get the drivers for this now. Is there no up-to-date drivers for Win8 64-bit? Worse still is the Bigfoot Killer Network card my anti-virus keeps saying its a Trojan so device manager won't recognize the device without those installed.

I have the motherboard drivers on the disc but yet again they say its not compatible with the OS. Any suggestions or help guys it would be much appreciated.
