Here is ASUS' top of the line LGA2011 motherboard targeting the gamer-overclocker market, the Republic of Gamers (ROG) Rampage IV Extreme. This board offers all the expansion room and connectivity you'll ever need, plus a wealth of nifty features that help overclockers and ease incremental upgrades. To begin with, the Rampage IV Extreme employs a strong digital PWM circuitry that supports heavy voltage-assisted overclocking with Vdroop control.

The LGA2011 socket is wired to eight DDR3 DIMM slots (two per channel). CPU and memory VRM areas are located along three sides of the socket, all cooled by heatsinks that are connected by heat pipes. These VRM heatsinks share heat with the one over the X79 PCH, which is actively cooled by a fan.
 
Expansion slots include four PCI-Express 3.0 x16 (red), of which two are x16-capable, and all are x8 capable, one PCI-Express 2.0 x4 (black, wired to the PCH), and an x1 slot. Storage connectivity includes four each of SATA 6 Gb/s (red) and SATA 3 Gb/s (black), and one eSATA, and a power-eSATA (unknown datarate). There are eight USB 3.0 ports (four each on the rear panel and front-panel headers). Surprisingly, there's only one gigabit Ethernet connection, the other connectivity option is Bluetooth, which plays a key role in some of the ROG-exclusive features such as ROG Connect. For once, ASUS did away with the Creative X-Fi soft-layer for its audio and the solution is pure Realtek ALC898 8+2 channel HDA codec (with Realtek driver).

Where do I even start with the toys overclockers get with this board? OK, first, the LGA2011 socket is designed in such a way that its Intel-spec retention bracket can be replaced by a custom ASUS-designed one, that modifies the cooler mount holes to make the socket compatible with LGA1366-ready coolers, so you can carry on with your expensive LGA1366-ready water-block. Second, there is a strong VRM that's backed by diagnostic phase and temperature LEDs, voltage direct-measurement points, and a EPU chip that marshals the power phases. There is redundant BIOS (in separate socketed serial EEPROM chips), with ASUS ROG-exclusive UEFI firmware. Thirdly, power is drawn, apart from the 24-pin ATX and 8-pin EPS, by a 4-pin ATX (CPU power) and a 6-pin PCIe, so electrical stability is maintained. The ROG connect feature lets you monitor and overclock your board from Bluetooth-enabled smartphones (hence the Bluetooth controller).

To top it off, every Rampage IV Extreme packs a free copy of Battlefield 3 Special Edition (bundles Physical Warfare and/or Return to Karkhand DLC(s)).

the bottom heatsink looks like it was made for sabertooth=boner kill
rest is amazing

I have a couple of the ROG boards.  This might be stupid, but on my other boards, there are two molex power plugs for extra juice for the PCIe cards.  Is one not needed now?

I think that would still be needed depending on the cards drawing power across the PCIe lanes. That really won't change all that much. I would still have one handy just in case. Until stated otherwise I tend to be a bit more conservative with my hardware.

The one thing I like about this board is that the top-most PCI-E 16x slot is set where the top expansion slot would be in a case. This would make the board useful for 7-slot cases with 3x GPUs and optionally one more single slot card such as a sound card. The board would also have 8 or greater expansion slot cases covered for 4x GPUs. Ideally the EVGA boards would have a similar slot layout.

Here is some more info. It seems like it's gonna have some pretty cool features. A graphical overlay for OCing, Also, it IS 4-way compatible.

I still prefer the EVGA solution along with the added value of superior customer service and support.
