The Most Powerful Desktop Processor in the World !  What more can be said ?

The Most Powerful Desktop Processor in the World ! What more can be said ?
I recently finished my latest Workstation build with this processor. I'm 65, a retired Aerospace Engineer and I still like to do a lot of CAD design and Rendering for my hobby now. This processor is INSANE Fast ! I have been using workstations in Aerospace for the last 40 years or so. Mostly high end, very expensive UNIX boxes. But I have never seen a processor the likes of this. Expensive? YES. But if you want the best in the world you pay the price. I can't believe anyone would ever be disappointed with the AMD Threadripper 3990x as the heart of their Workstation. This processor actually has an overclocking algorithm built in called "Precision Boost Overdrive" that lets you extend the boost clock to 4.5GHz. You just set it and forget it. I have never had a crash with PBO +200MHz enabled.
