"Way more than I would need". I'm a firm believer in there is no such thing as too much power. I see it as buying years on the back-end of usable life of your equipment. 5 years from now, an 18 core iMac Pro with 128GB of RAM will still be a solid performer with years still ahead of it.
I don't have a MicroCenter near me, but the last discounts have been tempting at a $1000 discount. The iMac Pro would likely be way more than I would need, but you can never have to much power. And MicroCenter seems to be one of the only retailers offer run discounts at That price range.
