This is my second ASUS motherboard. I have always found ASUS motherboards good for over clocking and lots of tweaking options. Wifi 6 is great and Wifi signal is more stable. The audio quality is good too.

Pros: Everything is where it is supposed to be.Cons: A BIOS flashback button would have been useful in updating a very out of date BIOS.
