Your ram is a bit overkill, 8 GB is already more than enough on a gaming computer, the only time you really need more RAM is if you're running a server or something. 16 GB isn't really necessary IMO, you won't see any real improvement in performance over 8 GB unless you have like 80 tabs of google chrome open at once or something. You could probably even get away with 4 GB of ram, but 8 GB is pretty safe and future proof in my opinion.
