AMD announced its first Zen 3 (Ryzen 5000 series) desktop CPUs on October 8.
Compared to Zen 2 (Ryzen 3000 series) CPUs, the Zen 3 microarchitecture has higher boost clocks and around 19% higher instructions per clock. A unified core complex die (CCD) allows 8 cores to access up to 32 MB of L3 cache, instead of two groups of 4 cores accessing 16 MB each, leading to lower latency and more cache available for any particular core. TDPs are the same as the previous generation, leading to a 24% increase in performance per Watt.
AMD estimates a 26% average increase in gaming performance at 1080p resolution, with the Zen 3 CPUs beating or tying Intel's best CPUs in most games.
Ryzen 9 5950X, 16 cores, 32 threads, boosts up to 4.9 GHz, 105W TDP, $800.
Ryzen 9 5900X, 12 cores, 24 threads, boosts up to 4.8 GHz, 105W TDP, $550.
Ryzen 7 5800X, 8 cores, 16 threads, boosts up to 4.7 GHz, 105W TDP, $450.
Ryzen 5 5600X, 6 cores, 12 threads, boosts up to 4.6 GHz, 65W TDP, $300.
You may have noticed that these prices are exactly $50 more than the launch prices for the Ryzen 3000 equivalents released in 2019. The 5600X is the only model that will ship with a bundled cooler.
The CPUs will all be available starting on November 5. AMD will stream an announcement for its RX 6000 series of high-end GPUs on October 28.

Like you, I've got a 3600 running in my latest machine. I'm going to be waiting for a price drop on the new CPUs, before I upgrade. I can also tell you now, you're likely to get more noticeable performance increases by switching from HDD *retarded slow speed* to SSD *400MB/s* or SSD to NVMe SSD *1600 to 3200MB/s*, than any upgrade you do.
I've been playing Space Engineers lately and it's a pretty demanding game. CPU usage goes back up and down not really hitting a lot more than 25%, while my RX480 has hit around 50-60% usage. Admittedly, I'm running at 1360x768 resolution on an old 32inch lcd monitor. With higher resolution it may increase CPU usage a bit. I would expect it to hit the GPU a lot more, though.
I haven't run Mount and Blade II: Bannerlords for a while, because 40GB+ update . . ., but that would likely be a much better game to test.
Really, just get something like https://www.nzxt.com/camapp [nzxt.com] and you'll see the usage while you play and record. Then, you'll be able to make a bit more of an informed decision on, "Do I actually need anything better than what I've got?". I thought that 32GB RAM may have been a bit of overkill, but looking at the usage in a game like Space Engineers, 16GB is almost too little. 32GB looks a lot better when you factor in running a music player, a browser, a chat program, and / or a streaming/recording program, while playing games.

yeah, when i upgraded from my bulldozer guts recently, i went with a ryzen 5 2600 for $125, but got an nvme ssd at 3000 MB p/s. the cp+ram is 2-3 times faster(IIRC) and the ssd is 6 times faster. bought the asrock hdv MB for like $50. very cheap guts and plenty powerful. maybe in 5 years i'll move up to zen4 or something. all i do is code and surf for the most part and the compile times are fast enough for me at this point. if i start writing huge compiled lang applications maybe i'll care more then.

Zen 4 could have a big (1 GB or larger) L4 cache stacked on the I/O die. That could contribute to the general IPC gains, or just benefit certain applications. There's also rumors [wccftech.com] of a graphics chiplet, so you might not need a discrete GPU anymore. Higher core counts are likely, e.g. 24 cores for a 5950X replacement. A TSMC "5nm" node should allow for smaller 8-core chiplets or 12 cores per chiplet.
If all of the above is correct, Zen 4 would be a great option for someone who wants absurdly high compute performance, but doesn't care about gaming (although an RDNA 3 chiplet might be sufficient for gaming too).

you can get a pci-e slot card that has a socket for sfp+ module. these modules have 10Gbps versions ... or if you have the estate ... 80km... from your pci-e slot ... errr ...

I've got a Ryzen 3600 but I put 32GB of RAM in it. It's enough RAM that I can have a 16GB temp fs all in RAM and run things off that, so I can completely bypass hard disks. That way you can easily saturate the CPU.

i've done some of this before, but didn't find a robust solution to things at the time. what are you using to sync between ssd and tempfs for persistance?

There are a couple solutions you can use. One is to increase the time data spend in the buffer before flushing. Another is to use a union file system. Another is to use a synchronizer like asd or unison or even a properly configured rsync. The most robust solution is a combination of the three.
