Many companies claim to offer the best overclocking for your money, yet only two compete for the best overclocking at the very highest price point. Today we put those claims to the test, including a full set of benchmarks to analyze performance gains.
The editors of Tom's Hardware do our best to cover the broadest selection of hardware that finds its way into your PC, but some components fall through the cracks whenever the steady march of technology pushes us to move on to the next new thing. Such was the case for a few X79 Express-based motherboardspriced over $380.
Reader John Case wrote in a few weeks after our premium X79 motherboard comparison to tell us that one of the products we missed wouldn't support any of his high-end memory at its rated frequency, no matter how much time he spent trying to optimize timings and voltage levels. After several successful RMAs, he was ready to ship us his board for testing. That’s when the manufacturer stepped in to provide a full refund.
We contacted that manufacturer (along with one of its closest competitors) to see how two of today’s top-rated enthusiast-oriented boards would compare to each other in terms of overclocking ease, stability, and features.

Asus and EVGA committed to this article with their Rampage IV Extreme and X79 Classified. We were a little surprised when EVGA instead sent its X79 FTW, but noted that this still fell within the $380+ ultra-premium market that was so scantly covered by only one board in our previous round-up.
