When configuring my workstation I was also considering the TR 2990WX.
However, due to the memory management, the 32 cores don't scale well with all applications, sometimes there is even a performance penalty.

I therefore chose the 16 core 2950X and am absolutely satisfied: it also has great single core performance (useful in many other applications surrounding photogrammetry, i.e. RAW image processing, point cloud editing etc.).

Currently there are also other top CPUs for photogrammetry (such as the i9 9900K), but they don't have the 3d rendering performance of 16 or 32 core TRs and they "only" support 64 GB RAM.

Here's a bench mark overview: https://www.anandtech.com/bench/CPU-2019/2260 (which is based on the older Photoscan 1.3.3 version).

Just for a comparison of the sequential read spead:
SSD: 3560 MB/s (my 970 evo NVMe)
RAM: 64575 MB/sec (at 2900 MHz)

So no, you'll never ever want to get into swap space (however fast your SSD), it brings the processing nearly to a halt (the processor cores are just not receiving enough data).

You may also want to check if "very high quality" is actually necessary for your anticipated output?!
Processing time increases exponentially between the various quality settings, and so does the amount of output data (with issues maybe in handling such large data in further steps?).
