Hello! I’m about to place an order for an iMac and I need some advice on which configuration to get from the two below: 21.5 inch iMac 3.6GHz quad-core 7th-generation Intel Core i7 processor, Turbo Boost up to 4.2GHz 16GB 2400MHz DDR4 512GB or 256GB SSD Radeon Pro 560 with 4GB video memory Magic Mouse 2 iMac 27inch 3.4GHz quad-core 7th-generation Intel Core i5 processor, Turbo Boost up to 3.8GHz 16GB 2400MHz DDR4 256GB SSD Radeon Pro 570 with 4GB video memory I plan to use it for coding, academic coursework, graphic design, occasional gaming, etc. Is there a big difference between an i5 or i7 processor? Are these configs good for long-term use? What others would you suggest? I’d prefer not go over 2k USD (I'm not in the US so the prices are higher here unfortunately). I plan to get an external SSD drive as well since I don’t like having too many files and stuff on my computer so I am okay with 256/512gb as I heard the SSD drive would be better than a fusion one. Thank you!
