OK, time to move this out of the order thread. I'm not going to show you an unboxing. If you are thinking of buying this, don't watch any unboxing videos, enjoy the quality packaging for the first time yourself (grin). Ships with 10.13.2. Basic "throughput plumbing test". Not a real benchmark but capable of telling us what idealized sequential throughput these are capable of: Next, Geekbench CPU and GPU https://browser.geekbench.com/v4/cpu/5708336 https://browser.geekbench.com/v4/compute/1629884 By the way, the GPU section completes in about 26 seconds. The app warns you it will take 2-5 minutes (grin). --- Post Merged, Dec 23, 2017 --- I'll continue to post first impressions here. Everyone else with one, feel free to jump in, I'm not claiming this thread exclusively for me --- Post Merged, Dec 23, 2017 --- Next impression: My iMac (late 2012 3.4GHz i7) is moving Lightroom original files to an external drive. It's much louder right now than the silent iMac Pro. But I haven't pushed the Pro at all yet. More to come later after I try a few games and import Lightroom and have it rebuild all the previews and look for faces.
