913 D series versus 910 D3

Is there a big enough difference for a 3 handicapper to switch from the 910 d3 driver to one of the new 913 d series driver? Will these new drivers be longer and more importantly more accurate? What will the spin numbers on the new series be and how will they compare to my current driver which is the 910 d3 with the RIP 60 X shaft set to C1.
