Okay, that's good, I'll have to look into liquid cooling. I think when I started looking at the AMD processors, I ran across the ThreadRipper series - what a beast - but 180W. I understand now that a high end Ryzen is < 100W.

I got a Lenovo P1 (that's a laptop, not desktop) about a year ago. It's got an i7-8750H and that's handled anything I've thrown at it. 6 cores, turbo boost up to 4.1GHz, it's fine.
Having said that, my work desktop workstation was acquired in 2013. It's got a Xeon E5-1650, 6 cores, 3.2GHz. It's slower than my P1 (I can tell from compilation jobs, although that could equally be because it has SATA SSDs, not NVMe), but can run multiple VMs fine.
And then there's our dev server at work - we got that around 2015, IIRC. It's got a Xeon E5-2440 v2, 8 cores, 1.9GHz. And that runs 6 VMs, 24/7 (we've separated out our Git, Redmine etc applications, but did it before Docker became a thing, so they went in separate VMs. One of my 'to-do' items is dockerising them, but it's never a high enough priority!). 5 are Windows Server, 1 is Linux. RAM is more of a resource than CPU, I've found.
I guess what I'm saying is - I reckon any modern i7 will be plenty good enough for running multiple VMs, given that ancient Xeons can manage it without a problem. Make sure you get at least 32GB of RAM, you'll be fine.

Yes, I know those sorts of reasons - the ones that would never fly in a properly costed business case, but are very important nonetheless My Lenovo laptop may have had some of those reasons behind its purchase as well...

I am still using a 3770k with 32G. It has 4 cores (8 threads) and I can (and have) run a half dozen different VMs at the same time, and never use more than 25% of the CPU. While I certainly won't recommend a CPU that old, pretty much any more modern CPU should do the trick.
I would recommend water cooling -- not necessarily a custom setup, but a "complete" system. They are nearly the same cost as a fan. Just put one in my daughter's new computer. Otherwise when your CPU does pull out all of the stops, the fans can get pretty noisy.
I do not game either -- however, I use a 1080 graphics card. Not for framerate, but to get good high resolution and for use in parallel applications.
And a SSD for drive C is essential.
The system is old, but other than a couple of GPU upgrades, it has been more than adequate development.
Now, if you need very large data storage, your cost can rise substantially by the time you implement a good RAID (preferably RAID 6).
After years (decades, when I think of it) of using client versions of Windows for development machines, and putting up with forced reboots after updates at random times - despite Microsoft's best efforts towards providing more "flexible" reboot options now given to users - I finally gave up a few months ago and built a Server-based VM for all my development work. Server 2019, more specifically. Primary reason: based on my experience, rebooting a server operating system has remained a sacro-sanct thing, in that a Windows Server would never, ever reboot on its own and you had to have an admin explicitly initiate a reboot process or at the very least, click on a Reboot Now button. I've had instances where a reboot prompt had been patiently waiting on the screen for weeks. Server would never take it upon itself to go ahead and do it on its own.
Long story short: I RDPed into that dev VM this morning, and was greeted initially by an empty desktop, and then saw a couple of Explorer windows being restored to a bunch of folders I last used. But all my running apps (including 2 instances of VS 2019) were gone. Exactly as might happen on a Windows 10 machine that just got rebooted. The following confirmed my suspicion:
So, it rebooted at 19:11:27 last evening. I know exactly what I was doing at that time. I had left my dev VM running, after telling it to go ahead and install Tuesday's updates, and left it alone once the download process was initiated. I then went to dinner, came back, and at that exact time, I know I was playing GTA5 on my game machine (a separate box).
This is now the second month in a row (just after Patch Tuesday) that this happens to my dev box. WTE, MS? I can't imagine this should happen on a server OS, in a data center, running important tasks. Why is this happening in my VM? (and no, the host OS was not rebooted)...
I can confirm what you are saying.
We actually had production systems running as VMs and they were set to not reboot but did actually reboot. Our IT dept investigated and had captured details and reported to Microsoft (via our service account) and at the time (a couple of months ago) MS said it was a bug.
I don't have the details but I believe there was a fix.
There's an option to allow the updater to automatically reboot a server?
I may have mis-stated that. I'm not sure there was an option to "not reboot".
I just remember that they all restarted and IT had said the way they had configured them was to insure that they did not reboot.
But, I agree with you about it being crazy. We were all astonished that the VMs had restarted and it was all related to the new update practices.
When I remoted into my Azure server this morning, I saw a notification that 'Updates were installed' and thought the same thing. Luckily I didn't have any work in progress and luckily customers aren't hitting that server when it restarted apparently at around 0400 this morning.
For Win10, I do appreciate the new little icon in the system tray that gives me some warning.
I run Windows, including an older server, the same way: via VM's . To manage all Internet activity, I purchased a router/firewall that has application control capability along with normal rules blocking/allowing.
Down at the office, we have 2 such. One of the categories is Windows Updates. I can control (either block, log or both) by all machines, some machines (or none). I can also set a schedule.
For the office, we have a wireless AP for customers and suppliers. It is on a separate public IP address with its own firewall. I block all social media (farcebook and such), webmail and other stuff. Block by IP in the firewall to block streaming. Costs money, but well spent AFAIAC.
Some time back, I set rules to block outbound to every IP group that Windows used to phone home. I think it required about 8 rules. Cut back on activity. Our routers have very flexible logging capability and built in Wireshark. Won't quote any brand names because every time I recommend anything, the recommendee winds up getting screwed.
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.
