I was looking at this build https://pcpartpicker.com/guide/VR8TwP/great-intel-gaming-build and was on newegg picking out the parts when newegg suggested i get the exact same motherboard except it was a usb 3.1 instead of a 3.0 to go with my cpu. This is my first build and I'm terrified of messing it up so I stuck with the one that is listed on the build guide as of right now. I'm wondering what's the difference between them and if i got the USB 3.1 would it negatively impact the rest of the build?

To have easy access for comparison I'll include the link https://pcpartpicker.com/products/compare/QXdFf7,FzGj4D/
The B250 is what is suggested and not the B250M
