OCC has published a review on the Asus P8Z77-V DELUXE motherboard

OK let's start with the obvious here. Performance wise the delta's between all of the boards in this comparison are going to be pretty slim for the most part. Intel's socket 1155 Second and Third Generation Core series processors with their integrated memory controller and core overclocking consistency have made it so that just about any board will give you a decent overclock and deliver comparable performance when you pop the same parts into it. To look at this even closer to home ASUS builds its boards to deliver the same overclocking experience in its Z77-based product stack from the lower end all the way up to the ROG Maximus V Extreme. Where the differences occur is in the feature set each board is equipped with so that just about every price point from the bottom to the top is covered. Kind of a modular approach when you look at it.
