I just had to make this decision. I ended up getting the base cpu and upgrading the ram to 32gb. I mainly work with capture one, resolve, final cut, affinity, etc… I can appreciate the cpu performance bump, but slightly slower speeds are something I can deal with. What I can’t deal with are crashes or freezes due to lack of ram. I had that numerous times in my 2017 imac with 24gb of ram.
While that is what I ordered, I will be keeping my eyes on benchmarks and comparison videos. I may continue to save and if the performance boost is in fact significant enough, I may return the computer and re-order and just deal with the wait. I have a feeling I’ll be pretty damn happy as is though.
