Asus M5A99X EVO R2.0 ATX AM3+ Motherboard driver updates

Solution
You don't technically need any of the Utilities, it will help you in some way but not necessary.

If you're using Win 8.1 64 bits.
Update the BIOS to the latest version. There is only one latest version.
That's all you need from ASUS apparently.

LAN and Audio from Realtek directly, for the latest version.
