So, this has been my primary machine for the past 3 1/2 years, and I've always been happy with KeyShot's performance using it. However, getting the opportunity to test AMD's new 16-Core Threadripper 1950X is showing a major upgrade in speed and performance. Just WOW! Still will be using the Mac Pro in my pipeline, as I only have ZBrush to KeyShot bridge for that system at the moment. :)
