In a change of pace here on ROG, Canadian reviewers, Hardware Cannucks, have had a look at ROG's brother in arms - the Sabertooth X79. In their 17 page epic Sabertooth X79 review, they conclude by giving it a Dam Good award, and stating:
"Similar to the Rampage IV Extreme, we found it difficult to find much to complain about with the Sabertooth X79. ASUS has done an excellent job with their X79 boards and competitors will have to up their game to even stay close."
If you're in the market for something hard wearing in all conditions, solid overclocking and with a 5 year warranty in most regions - take a further look at the Sabertooth brand.
