Yes it is compatable http://www.intel.com/support/motherboards/desktop/sb/CS-008326.htm.
In a desktop board with the excpetion of some Intel® Atom™ processors all use EM64T. EM64T means that the processor will except 64bit memory instuctions and address greater then 4GB of memory but it doesn't in any way stop you from using a 32bit OS or program.
Besides some Intel Atoms the last processor that we had that wasn't 64bit was the Intel Core Duo in laptops.
