The 27in 5K iMacs jump from Haswell to Skylake – which is two CPU generations, they also move up one GPU generation, and the storage bandwidth is twice as much. In addition, the display quality is better than ever and you can buy 64GB of third-party RAM as a user upgrade. All this adds up to a pretty impressive update. Our main criticism is that the Fusion Drive isn’t standard across the range, and, even worse, the SSD part is now much smaller. However, the new 27-inch iMac line-up is great value for money, if you were to purchase a 5K display of this quality it would cost a lot more than the price of the 5K iMac, and it wouldn’t come with a fast, capable, fully functioning computer

If you were to fully spec out the ultimate top of the range build-to-order (BTO) model you could get: 4GHz quad-core i7, 32GB of RAM, a 1TB SSD, and faster AMD Radeon R9 M395X graphics – it would cost you £3,289. £1,440 more than the standard top of the range model, and just £10 less than the top of the range standard Mac Pro, which costs £3,299.
