This is something i would be considering around Jan/Feb next year. Did you have any initial stability issues with the upgrade? I've read conflicting comments when going with the new Ryzen chips. My 4770k is happy at 4.5ghz and has been for 4 years now and I'm a little loathed to upgrade, since it works perfectly.
I felt the same way. On the initial BIOS I had some difficulty getting the RAM to run its XMP profile, some difficulty getting the OS installed, and there were also intermittent WHEA errors. Since then it's been 100% stable, not even an application crash, and the WHEA errors have stopped. Performance has been very good, not only in terms of gaming frame rates but the extra cores have made a big difference with how much I can have running without having to worry about it.
Just for reference I went with the following kit:
AMD Ryzen 7 3800X Eight Core 4.5GHz (Socket AM4) Processor - Retail
Team Group Dark Pro "8Pack Edition" 16GB (2x8GB) DDR4 PC4-25600C14 3200MHz Dual Channel Kit
Gigabyte X570 AORUS PRO (AMD AM4) DDR4 X570 Chipset ATX Motherboard
+ a cooler, and reused the PSU from my previous build.
