Upgrading a 4670K? Worth it?

[Morphex]

Heya fellows,
I need some insight on whether is worth upgrading my I5 (currently at 4.2ghz)  to a ryzen 1700 now. (yeah I know a 8700k just came out, but I am not sure if the 100$ extra are worth the price, or maybe go with a cheaper 1700 and upgrade next year again?)
I do game a bit, not hardcore gamer, and I use my desktop mostly for development (web, windows, etc). The core/thread count is the main thing I was looking at, I didn't upgrade once they came out because I am not sure I felt the need to upgrade, but most recently on a larger project I have been feeling that perhaps the core/threads would really help me with my compile times and development performance as whole.

I am mostly looking on opinions on developers, that have upgraded and if it was worth the upgrade.

The software I am most interested in is mostly NodeJS  (Webpack,React,... etc, the full deal basically) , Visual Studio (C# mostly), with Unity3d as hobby.

If you have any feedback I would like to know.
Thank you.

P.S I do intend to OC the Ryzen cpu when upgrading.

If your development work is for applications, both local and web app related, you don't really need a powerful processor to do development work. The only time you really need it is if the project you're working on is humongous and complex and you really would like faster iterations. The only thing I can see needing faster hardware is Unity, but I also don't see that needing a high-end processor either.

 

So really, the real question is, are you dissatisfied with whatever you have right now? If not, then there's no real reason to upgrade.

Yeah, that's the thing, the i5 has been working pretty much fine, and its not bad per se, I am just really checking to see if the upgrade would really improve on a noticeable scale on those use cases. I do pin my cpu at 100% while developing/compiling, which is not a bad thing, but its noticeable for a few mins. 
One thing that does come to mind, is Light Baking in Unreal/Unity3d, which would greatly improve due to the more cores, but this is a secondary workflow, so not a major deal.
