I am currently using a 2019 5K iMac. I need a PC for another project (I only have room for one display) but still want to use a mac for my lightroom and photoshop work. I am thinking about the i7 mini w/32gb of ram and a BenQ SW271 27 Inch 4K. I know the mini does not have a GPU but will that matter with photoshop and LR or will I need a egpu. As a hobby I shoot with a D750. I am real happy with the iMac screen so I looking for a suitable replacement. Is there any thing else I should be looking at in the BenQ price range.
