The issue with the Maximus II and just about every other Asus ROG is the north ,south bridge heating up along with the mofets and power circuits.
most of the time you need to remove the heatpipe and use a better TIM or go for broke and water cool the board which makes the Asus the better board if you can control the temps.
I am more comfortable with Asus and never had good results from Gigabyte.
I guess I just like drama
