We're only beginning to get to grips with the immense performance and overclocking headroom of Intel's new Sandy Bridge processors. It's therefore difficult to draw really firm conclusions about the comparative performance of the first compatible motherboards.

However, what we can say for sure is that the Asus Maximus IV Extreme RoG is making the most of the 2.0 revision of Turbo Boost that comes with Sandy Bridge. During testing, the Maximus runs an Intel Core i7-2600K processor at a constant 3.8GHz under load, regardless of the number of active cores.
