Although the OP probably does not have any 64 bit user applications
installed he will get the benefit of the OS itself being a 64 bit program
means that the new 64 bit instructions which combine the contents of 2 32
bit instructions can execute in one machine cycle instead of 2 machine
cycles using a 32 bit OS.
Also the OP would get the benefit of moving blocks of data 64 bits per
machine cycle instead of 2 in the 64 bit OS uses has 64 bit registers
instead of 32 bit registers
