Overclockers Club published a review on the ASUS Sabertooth X99
A quote from the article:
Good looks are just one part of the equation, since this board is built with a plethora of military spec hardware that ensures the Sabertooth X99 is going to be around long term. To make sure you make it well past the five-year warranty, ASUS does some serious burn-in testing and compatibility checks. Using 1000+ devices over 7000 hours, you get incredible hardware compatibility checks to make sure that everything works. From a performance perspective, if you run the same hardware and factory defaults in the BIOS you are going to see similar performance results across the board when comparing the Sabertooth X99 to any other X99 motherboard. That is really an expectation, but it's the overclocking performance and reliability aspect of this board that sets it apart from the masses.ASUS Sabertooth X99 Review @ OCC
