Ryzen 5 1600 constant stuttering

So I built a new PC and decided to use Ryzen 5 1600 expecting it to run anything at high frames. In reality I get huge stutters (in the picture attached) which ruins games entirely (FPS drops from 80 - 120 to 20 for 1 sec).  I installed latest bios, amd drivers - everything, it got better but its still really annoying and makes most games unplayable.

 

Parts list (if that helps):

Gygabite G1 1070

Ryzen 5 1600

MSI 350B tomahawk

Corsair 550W

2 x 4 DDR4 2800mhz
