Ryzen absolutely dominates in workstation loads. Video editing, rendering, animating, coding, streaming, transcoding, and much more.
It also games very well when paired with fast RAM, and soon optimizations will come in and it will be a better CPU.
For example. I want to make my own videos and edit them, stream, render basic animations (just for fun), make some artwork like logos, and code. I'd also use it to make stop motion, edit my photos from my camera. It's really useful for this.
And I'd also be gaming. A lot of gaming too. Ryzen 1700x with 3600mhz CL16 RAM is like a 7700k in gaming, so it'll do my job well.
I am expecting it to get even better. But even if it doesn't, a 10 FPS difference won't ever make up for the 40-50% workstation performance increase compared to a 7700k.
