After thinking about it for some time now, I finally purchased a brand new Mac Pro in late December 2017. I've been waiting to test everything and make sure it works as it should, and it's been performing flawlessly so far. It replaced my 2010 Mac Pro (2.4GHz 8-core) and I couldn't be happier with my purchase. It's a 6-core/D700/16GB/512GB SSD configuration which I will upgrade to 64GB soon. Paired with Benq SW320 4K monitor and Drobo 5C for storage + additional external 1TB SSD. I use it mainly for my commercial product photography business and 4K video editing in FCPX. I've been going back and forth between it and 2017 5K iMac, but I already have brand new 5K iMac at the office (quad-core i7, 1TB SSD, 32GB DDR, Radeon Pro 580 8GB) and I don't really like it to be perfectly honest. Yes, the 5K screen is amazing (more attractive than accurate though) and the system is very fast, but it's also noticeably loud and I feel like it's going to start melting away while rendering 4K video or processing large amounts of photos in Lightroom or Capture One Pro. Call me crazy, but I highly prefer super quiet Mac Pro and stand-alone, accurate color profiled matte screen. It stays cool and quiet no matter what I throw at it, and the processing speeds are on par with iMac. No matter the benchmarks, it simply feels snappier and more fluid in my daily tasks. Yes, it may be old tech these days, but I would definitely buy it again 🙂
