Your E5-2699 v4 with 22 cores (44 cores total and 88 threads) option is a looser as Premiere is limited by Microsoft software to 64 threads so the second processor has to be turned off or hyperthreading must be diasbled
I was leaning towards the other processor anyway since many things are still single-threaded anyway and the extra clock speed would help that. Thanks for confirming!
....you may want to consider comparing the price and performance of the new Broadwell E CPUs that are now on sale. With PPro, CPU clock speed is king, and the Broadwell E CPUs offer substantial overclocking ability in addition to as many as 10 physical cores on the flagship CPU. Eric Bowen on this forum has a thread showing his test results of the new 6950X CPU....soon he will be able to show the comparison of Xeon to the new Broadwell E. He would be the person to explain the difference in performance between those two CPU models.
The above assumes that you do not already have a motherboard in use which commits you to a choice of Xeon only.

Good thought! I've been wondering about that. If we were just pure shooting and editing, that'd probably be the way I'd be leaning. However, the majority of my work is in Cinema 4D and having a huge amount of processing power is very handy for that. Plus contingencies are nice, so if my machine goes down in the middle of a critical project in C4D, I can just hop on another machine, install C4D and go.
If the powers-that-be come back and say our request is too high for their budgets. I might try to keep the request for the two C4D machines with the Xeons, but request the four Premiere-only machines with the Broadwell E CPUs...(I mean, they won't be slouches for C4D in a pinch... )
