Ok, so in the end I almost completely changed my setup, and ordered the stuff, should arrive next week.
I ditched the AMD setup, as I was talking with some guys at PC Hardware, and they suggested that in my case I could also go with an Intel CPU, because it still has single core superiority, and has a good multi core performance, basically the better option.
So this will be my setup:I really think you'll be good with a Ryzen 2700x system based on your use-case... But if you say money isn't a huge issue, the 9900k will somewhat offer you the best of both worlds in terms of single core and multi-threaded performance in general. 8 cores 16 threads is nothing to scoff at, and the higher IPC/clock speed on Intel does handily beat out Ryzen, but the cost difference is quite a lot..
Coming from the i5 750, you'll see a massive jump.
Also, AMD is so threatened by the 9900k they're going to launch with 12 core Zen 2. With it's expected 20% faster performance, that will just barely match your 9900k in productivity. We will see if they can actually price it lower.
I expect you'll get at least five years out of the 9900k, if not more. And you can buy it today, instead of six months down the road.
