Hi guys, Rarely post here but hoping you guys can help me out.... I'm looking to buy a 27" iMac - the most intensive things I'll be doing is photo editing in Lightroom/Photoshop. Will also have Windows 10 via Bootcamp or Parallels (TBC which). There's an iMac going on Gumtree for £1,500 - specs are: Intel I5 Kaby Lake processor - 3.4 GHZ Turbo Boost 3.8GHZ RAM - 24GB (2x 4GB factory, 1x 16GB post) Radeon PRO 570, 4096GB memory 256GB SSD Magic Mouse and apple keyboard included Was purchased in April this year and therefore is covered for repairs & service until April 2019. The machine has barely been used (a little video editing) and comes in box. The seller is selling due to wanting a laptop for portability. I know there's a potential refresh coming, even as early as September. But you never know how big the upgrades are so thought I'd snap at this while I have the chance. What do you think? EDIT: it's the mixed reviews of the 570 that have me a little nervous.
