Yes you would, if you would ever use the eathernet connection. If you wouldnt then you dont need to installthe drivers. I reccomend that you do just incase your wireless usb adapter fails one day. If you dont install drivers then the operating system has no way of communicating with your ethanet card. Eg. I was new to a computer and didn't know how to use it so my dad had to help me.
Sometimes operating systems like 7,8,8.1 and 10 install drivers whithout you having to install them but this is rare on gmaing motherboards.
Hope this helped!
