Dont think so, the sandy bridge uses socket 1155 not 1156.
I don't think that's a good mobo choice for the CPU, no (look for 1155 socket).Also be sure to run a 64-bit OS to make use of all that memory. Is this build solely for Skyrim? If so, I'd wait a while longer (by the time Bethesda release system reqs, it's a good bet there'll be superior hardware available for the same or lower cost).
Yeah you guys are right, changed the motherboard to 1155 socket.
