7980xe’s are dirt cheap nowadays just get 1 of those.

However, be careful about your VRM if it is those first batch of X299 boards. The first batch of those boards has underpowered VRM’s due to the board partners severely underestimating the powerdraw of the 18 cores, and they have a tendency to overheat.

If your board is one of those, you may want to top out with something less like a 7940X. Make sure to have adequate airflow.
