The user, a professional art photographer, wants to get an iMac Pro.
They have a large Lightroom catalog of photos that they work on - over 150,000 photos. They do all their adjustments in Lightroom
, and don't use Photoshop (although they may want to in the future) Lightroom needs to display several hundred previews that can be scrolled at a time, and they would like the previews to scroll quickly.
So - although they are looking for fast display of multiple images, they are not doing any video editing, 3D rendering, or VR.
They already have a 2.5 year old iMac with i7, 16 GB of RAM, and the video circuitry with (I don't recall) maybe 2 GB of VRAM
I was going to recommend an iMac Pro bumped to 64GB RAM, and the Radeon Pro Vega with 64 of VRAM.
I am not sure if increasing the configuration to 10-core Zeon will make a significant difference with Lightroom or Photoshop in the future.
Any advice on the most satisfying configuration for the iMac Pro?
