The LGA 2011 socket is the one reserved for Intel's mightiest CPUs, the Ivy Bridge-E (which won't be out for months) and the Sandy Bridge-E (which are already out).
MSI's motherboard is called X79A-GD45 Gaming and has 8 DDR3 memory slots, six PCI Express slots (one mini, five full) and all the overclocking features people can think of.
MSI also decided on a black and gray color scheme, with die-case MOSFET covers and heatsinks for the chipset.
Sadly, Micro-Star International did not give an ETA (estimated time of arrival) or a price.
Then again, the mainboard is almost identical to the X79A-GD45 (8D), which suggests the sum of around $200-201 / 200-210 Euro.
