With all this talk… I’m eagerly waiting for the iMac Pro.
Best of all worlds really: - High core count - ECC RAM - 5K 27” display - Great graphic card - Super silent… I’ve been using a Mac Pro 2013 (the trash can one), Xeon E5 8 cores, 32 GB ECC RAM, connected to two 27” screens (one 5K with DPI set at 200%, the other a 2560x1440 Apple thunderbolt) It runs flawlessly Windows, Mac and Linux (though under Linux I never managed to get more than one screen working at a time). It compiles on mac, even with stylo under 12 minutes and on Windows in 19 minutes (used to be 6 minutes and 12 minutes respectively before all this rust thing came in)…. And that’s using mach with 14 jobs only so that I continue to work on the machine without noticing it’s doing a CPU intensive task. The UI stays ultra responsive. And best of all, it’s sitting 60cm from my hear and I can’t hear anything at all… This has been my primary machine since 2014, I’ve had no desire to upgrade as no other machine will allow me such comfortable development environment under all platforms we support. It had been difficult to choose at the beginning between the higher frequency 6 cores or the 8 cores. But that turned out to be a moot issue as the 8 cores, when only 6 cores are run will go as high as the 6 cores version… The mac pro was an expensive machine, but seeing that it will last me longer than your usual machine, I do believe that in the long term it will be best value for money.
