CPU not Performing as expected

Hello guys,
I recently got a GTX 1070, the thing is I think that my CPU is not performing as expected
I did a format after I installed the video card
and I don't think it is a bottleneck my CPU can handle this card pretty well
here are my specs:
Motherboard: MSI H170 Gaming M3
CPU: intel Core i5 6600 @ 3.3 Ghz
GPU: Gigabyte GTX 1070 Windforce OC 8 GB
RAM: 16 GB DDR4

you can find a screenshot in the attachement of the fire strike benchmark test in comparison with another bench
as you can see the other user has the same CPU but with 25% better performance in the physics score
