I bought the EVGA Dark motherboard (that was before the 390 came out) so I'm still trying to figure out the cpu.
I have everything except that to finish my build.
Should I spend the $2000 on the 18 core i9 (because SETI uses gpu cores and cpu cores) or can I get away with something cheaper?
I would love your peoples opinion.

The "new" Intel X-series CPUs for socket 2066 are just about ready to drop @ ~ 1/2 the Price
 
Intel has already announced they are cutting Retail price of existing CPU up to 50%
 
I'd wait for the new CPUs   i9-10980XE

i9-10980XE it is then.

If you plan on doing primegrid once in a while, you may want one with dual AVX-512 chipset.
I believe x299 CPUs have it. Maybe Bcav will chime in, I know he has a couple.

All three of mine have 2 AVX-512 FMA Units
https://ark.intel.com/content/www/us/en/ark/compare.html?productIds=126695,126240,123613

The i9-10980XE is not listed but I don't prime grid (I do SETI).

It's interesting that my new rig (Ryzen 2600X, EVGA 1080 Hybrid is reporting 141,000 + WU's) while my EVGA X299 FTW-K, i9 7900X, RTX 2080 Ti Ultra is reporting 139,000 + WU's.
I think that because  I do snooze BOINC ( on my EVGA X299 FTW-K, i9 7900X, RTX 2080 Ti Ultra) when I play games and convert files and the Ryzen just works the SETI.
Anyway, I want to buy a new case for water cooling a RTX 2080 Ti Ultra air (I bought the water block for that card from EVGA) and for my new i9 cpu (not bought yet) and bcavnaugh suggested EK water parts
and I want to water cool the cpu too.
Price is not a factor but easy maintenance is.
Soooo, what would you buy?

The Intel® Core™ i9-10980XE Extreme Edition Processor has 2 AVX-512 FMA Units

Myself I only run GPU Tasks over on Seti and allow the CPU to run other BOINC Projects like;
 
  and a others.
