ECS put out the X79R-AX Extreme and it certainly deserves that moniker.  They went for 4 USB 3.0 ports instead of 2, they included a CLRTC button on the back panel, dual NIC s and Bluetooth and as well as WiFi with an external wire style antenna.  Internally there are 8 SATA 6Gb/s ports and 4 SATA 3Gb/s ports, a diagnostic LED which also displays current CPU temperature and 4 PCIe x16 slots and 2 PCIe x1 slots.  That list goes far beyond the other Extreme X79 boards on the market.  Guru3D warns that the BIOS is more than a little confusing when you overclock but at roughly $300 to pick up when it becomes available this is a sweet example of an X79 motherboard.

"Today we take a look at the new motherboard from ECS, the X79R-AX Extreme. We’ll throw in a decent photo-shoot and a benchmark suite at the product and get an indication what performance is like with the Intel Core i7-3960X (Sandy Bridge-E).

Admittedly I was a little shocked when the motherboard arrived, as it is probably the most feature rich X79 motherboard we’ve had in our labs."
