I am super new to mining and just want to make sure I am doing it right.

B250 Mining Expert Motherboard
I3 intel processor 4400

I am running nicehash miner and when I check the Task Manager my CPU is at 99% and my GPU is at 6%.  I am wondering if I am not getting the max load I can be getting out of my GPU or if this is normal.  

Should my GPU show higher in the task manager?
