I have recently built a machine with Ryzen 2700X & geforce gtx 1050ti (GPU is required as Ryzen doesn't have an internal one but there are plenty of cheaper ones like mine), running Ubuntu and it's just fantastic. Docker builds, compilation takes seconds as compared to my macbook which has i7. Plus there's no overheating issues when I am running Kubernetes all the time and I can still code.

TL;DR Ryzen 2700X is great value for money, would recommend it any day :)
