Here's a prototype ASUS board with the LGA2011 socket. Flanked by four DIMM slots that work together to form a quad-channel memory interface, the huge socket dominates the centre of the board. Indeed, it's so big that it requires two levers to keep the chip in place.
The X79 Extreme4, pictured below, supports the upcoming Sandy Bridge Extreme chip that's presented on an LGA2011 form factor. The chip is going to be huge, evinced by the size of the socket, and it's flanked by four memory slots that combine to offer quad-channel throughput.
