That motherboard may require a BIOS update before using this CPU, and would not support overclocking either, but yes it could support it.

Q: Will it work on a Gigabyte GA B85 HD3-A motherboard?
Answer by Website User on 22nd January 2018
This processor will only fit in the socket type 1151, as your motherboard has the 1150 socket this will not be compatible. - Matthewt

The native speed is 4.2GHz but under load it will auto turbo/ boost itself up to 4.5GHz. With it being a K version of the i7 7700 you can overclock it yourself further.
