ASRock X79 Extreme11 Intel LGA 2011 @ techPowerUp
 

The ultra-high-end ASRock X79 Extreme11 is fitted with an onboard PCIe 3.0 LSI RAID controller, and not just one, but TWO PLX PEX8747 PCIE 3.0 switches. The ASRock X79 Extreme11 really does take it to the Extreme, offering functionality and capabilities no other motherboard can claim. But does it perform to the Extreme?
