Just wondering if anybody has experience using an iMac with similar or same specs as below, and their experience using both Lightroom 6 and Photoshop CC? Currently using a 13inch MBPr (Base early 2015) and its pretty quick, and dont want to suffer a performance loss. 3.3GHz i5, 24GB RAM (8GB Apple + 16GB Corsair), 256GB Flash Storage (3TB External Drive for main storage), R9 M395 2GB GPU Any help would appreciated, I have no idea what to buy in terms of specs! Am a photographer and graphic designer. Also would you suggest 256GB Flash + External Drive, or 2TB Fusion?
