I'm looking to buy an 2017 IMac, however I'm not sure which model will be the best buy. I will use it for the following task. - Maple to solve and visualise mathematical problems - Spreadsheets (not super heavy) - Lightroom (hobbyist) - Final cut (hobbyist) - Casual gaming I'm considering between these two Option one 3,5 Ghz i5 8GB ram 512 GB SSD Radeon pro 575 Option two 3.8 Ghz i5 8GB ram 2TB Fusion Drive Radeon pro 580 The price is the same for both in my country. I plan on upgrading the ram down the road. Which would you choose? Thank you in advance.
