@scottalanmiller So, If my average CPU usage on one of the hosts is over 50% and max is 95% for the past 6 months, I can't use that to say how much more CPU I need if I wanted to double the number of running VMs with similar performance needs?
How can you define similar, though?
Whatever my average CPU utilization is for my existing VMs on my existing hosts with 2 x Intel Xeon E5-2609 v1 CPUs.

Do you have any issues with high CPU ready times today?
Here is the CPU Ready chart (previous month) at the host level for the first host . It has 9 active VMs.
Here is the CPU Ready chart (previous month) at the host level for the second host. It has 17 active VMs.
The differential between the two, in terms of number of VMs, is due to the current storage constraints. One of the VMs on the first host has significantly greater storage usage than all others. This has grown over time and forced the uneven allocation of VMs and has compounded over time.

Is there a reason to expect the company to be adding so many more computationally heavy workloads?
I don't know that we would be doubling it, I was just using that as an example on how I can associate some numbers to this planning process. If someone says, we are spending $25K per server, how much more capability/capacity do we get from our investment? For RAM and storage, that is easy- Faster and greater RAM and storage capacity, adding tiered storage by introducing SSDs in RAID5 and using NLSAS in RAID1 for "bulk" storage.
Apparently, due to the complexity and advancements in CPU tech, there isn't an easy way to calculate or express a tangible value for it.

What kind of processing are you doing that is eating up so much CPU today?
I have several Windows Server systems using different DB technologies, like my ERP (not even sure what the DB is) and MS SQL (WSUS, PRTG, PDQ, Veeam BR, Veeam One, etc). FileMaker (more RAM intensive) and MySQL (Fishbowl Inventory). I have a 2008 R2 RDS server, that is being migrated to Server 2016. Based on my experience with the current environment, Server 2016 uses more CPU than previous versions- Especially during Windows updates. I also have 3 Windows file and print servers, but they are more disk than CPU.
On one host, the most CPU intensive are a Ruckus wireless controller and PRTG monitoring server. - Currently, showing as 31% and 36% CPU utilization, respectively.
On the other, the most CPU intensive are PDQ Inventory/Deploy, Veeam BR and Veeam One and the current RDS server. Currently showing as 30%, 33% and 11% CPU utilization, respectively.

That's a bit different. You can estimate the amount of "additional capacity" available. The question becomes... can you put a value number on that additional capacity?
That was also my question. If I could (and knew what it was), I would be able to more than take a shot in the dark for choosing the new CPU. Currently, I stopped at 16 cores for Windows licensing and CPU/hardware cost. I only chose 1 CPU per server, due to the performance overhead that you and others have talked about when using more than 1 CPU with other specs being the same.

As I explained in another thread, I am trying to build out 2 new ESXi hosts. I currently have 2 R720XD servers, each with 2 - Intel Xeon E5-2609 2.4 GHz (v1) 4-core. I am looking at replacing them with 2- R740XD servers, each with a single Intel Xeon Gold 6242 2.8GHz (Turbo 3.9) 16-core.
This is the only benchmark I could find. The 6242 only has 1 benchmark test sample, so it is hard to say how much weight it holds.

My question is, when using my existing servers' performance history, how can I use that to see how much of a benefit, the new CPU would provide?
I have had the same questions. Will check out Nodegroups, as @black3dynamite suggested.

I just tried modifying UAC again to never notify. When I go into UAC as my admin account, it is set to never notify. If I go into UAC as the user, it shows as the one just below the top. How does that make sense?
No. It should be system wide. If you set it to never ad admin, it should be never for everyone. Is it on a domain? Is there a GPO stepping on you when logged in as a user?
I don't have it set in the GPO. I went in and checked it twice. Rebooted in between adjustments.

Depending on the video cards, that might be an issue.
