I am purchasing an iMac next week & have been going back and forth over a coupe of options. Price is a factor, "starving student" and all that jazz. But I want to be sure I am making the best choices for my needs... where I should/shouldn't cut corners. I am c My usage: I am a graphic design & photography student, heavily using Illustrator, Photoshop, Lightroom, etc. I am debating between: 21.5" 4K w/ 16GB, 3.3GHz quad-core Intel Core i7, & 2TB Fusion @$2029 USD OR 27" 5K w/ 8 GB (upgrading to 32GB on the next paycheck, $264 from OWC), 3.2GHz quad-core Intel Core i5, & 2TB Fusion @ $1969 USD + $264 memory upgrade I am less worried about the graphics, as either of these are a HUGE improvement on the graphics of my current 2009 MBP. Main questions: For graphics & photo creative programs, will 16GB be enough? Or will I be wishing for 32GB? For my uses: is memory more important than a speedy processor? Does it make sense to have 32GB with 3.2GHz quad-core? (As I understand, if choosing 32GB, it's best to bump up the storage to at least 2TB Fusion.) Much thanks in advance!
