Gaming PC Set Up

Not at my PC currently but here are my specs:

Intel i7-7700K 4.6Ghz
Radeon RX 470 (major upgrade needed here, still runs well though)
8GB RAM 2400hrz
1TB WD HDD
Cryorig H7 Cooler

I also have the Razer Black Widow Chroma X keyboard and Lancehead Tournament Edition mouse. I need to look into getting a SSD and upgrading my graphics card as soon as possible to at least a 1070. My setup does what I need it to do for the most part, does anyone have suggestions on how I could potentially improve it though?
