So I finally decided to purchase an iMac after years of using the regular windows PC. I dived heavily the past couple months in programming and photoshop designing and I felt the need to pick an iMac. That doesn't mean I haven't used macs before (I have all apple devices except for the iMac) I have stumbled across the two mid-range and premium products. One costs 1799 and the other is 1999. My question is, do I really need the SSD drive for programming and photoshop design or will the 2 TB fusion will be convenient? I would of course as well still do heavy surfing and web streaming (youtube and twitch). a 2 TB fusion or 256 GB are the two best options for my budget, can you advise per said about my purpose?
