iMac 5K (Late 2015) with 64GB: the Key to Professional Usage
Get the new iMac 5K at B&H Photo and see the MPG computer gear wishlist.
MPG recommends this iMac 5K: 27" Retina 5K Display, 4.0 GHz Intel Core i7 (Skylake), 1TB Flash, 8GB memory, AMD Radeon R9 M395X GPU (4GB GDDR5) + 32GB or 64GB OWC memory.
All prior models of the iMac 5K have long been handicapped by a 32GB memory limit, thus forcing professionals to the Mac Pro.
The late 2015 iMac 5K changes the game by accepting up to 64GB memory, which makes it far more viable for professional photographers like diglloyd, videographers, etc*.
For example, MPG digloyd’s everyday work cannot be done efficiently on a system with only 32GB memory, as the screen shot shows from work just last night.
Apple does not offer a 64GB memory option, but OWC has a 64GB memory kit that costs only a little more than what Apple upcharges for 32GB, making the iMac 5K an awesomely fast Photoshop or Lightroom workstation at a far lower price than the Mac Pro. If a full 64GB is not needed, add memory to what shipped with the iMac 5K.
* Some iMac 5K drawbacks remain, name only two Thunderbolt ports (on one bus), which is problematic for multiple displays in particular, but also for multiple high performance devices, or device-to-device copies (bandwidth restrictions). Also, the Mac Pro can go to 128GB for really huge jobs.
