The 2990WX has four chiplets on a carrier and only two of them have direct access to RAM. They can only share access to cache. The 2950X has only two chiplets and they both have direct separate access to RAM. Also, the heat produced by the 2990WX will probably mean that they will not all run at full speed. So I don't think the 2990WX is worth the expense. It's single-thread performance is not as good as 2950X. Also, you might wait for the 3950X because it is due out in the next month or two. Also the 2950X will drop in price when that happens.
At-face clock speeds really don't mean much. The 2990WX outperforms the 2950X in single-threaded performance, and is only at a loss of 4% to Intel's i9-7980XE in single threaded performance. Additionally, the 80MB L2/L3 specifically addresses the issue you spoke of over the 2990WX's 40MB. Has anyone tested the 2970WX considering it's suppose to allow 24 cores to work simultaneously with 48 thrads, and a better price per core over the 2950X.
Heat management should be a concern on 250w or 180w with use in TG or other workstation tasks, so there is no real "one over the other" it's just about adequate cooling systems for either. Like always, considering ambient temps of houses, and cycling rates, I do not suggest going water cooled for TG. You will be heat spiking your CPU and it is not recommended. Fans will always be smoother and a more responsive heat curve when it comes to random heat speaks under full load. This is why water cooling is not as popular in commercial scene like data-centers and render farms. Just get A/C for your office or create a custom heat curve for your fans.
I've attached a image which shows you the heat spikes I've spoke of time and time again. They will cause hiccups in computation and slow things down momentarily, and they're harder for water cooling to manage. Same system, different cooling systems. Same CPU stress test, ran several times accounting for variables. Almost down the line, the liquid cooled system obtains higher temps, and more aggressive peaks than fan which had substantially fewer, with more controlled response time.
Water/liquid cooling is a gimmick outside of gaming. For moderate CPU tasking it's great, you won't see anything but performance, but not for heavy tasks.
