I wasn't to sure about Ryzen when it came out due to the 1080p results but in hindsight I can see some of the testing was a bit iffy and with updates etc you could expect to see improved performance. Also games down the road were more likely to be taking advantage of the extra cores then not which gives it the edge over Kaby Lake.
I'm running 1440p and really with two strong 1080s they absolutely nail it... but the CPU struggles with high frame rates to keep up on 144hz.
I think I might take a punt on it in a few weeks, if it turns out to be a nightmare then nevermind as I'll probably learn a lot along the way.
