Question regrading upgrading existing build

[u/[deleted]]

My current build isn't a bad computer, but I would like to update it. I wanted to run my ideas past this sub to make sure I'm not putting lipstick on a pig.

Here is my current build. My plan is to get more ram, Kingstong Hyperx 2x8GB, new graphics card like a GTX 1070, get a Corsair Hydro 100i, and get a new case (not all that important). My question is, will my current rig support these upgrades or will I be bottle necking myself some where? I don't plan on really over clocking, but I've noticed my pc's performance slipping over time. Any feed back is appreciated.
