I am a full-time creative photographer with a Lightroom+Camera Raw+Photoshop workflow and I need to replace my aging 27" iMac. I currently use a Sony a7R II but will replace it with an a7R IVa (61 mp sensor) or perhaps the forthcoming a7R V. An image from an a7R IVa saved after a handful of fairly simple Photoshop edits exceeded 1 GB in size and I do heavy editing, so I can image my files approaching 2 GB in size. Thus I want to make certain that Photoshop running on my new system can handle files that large (without, for example, waiting 5-10 seconds for a selection to be processed).
I am considering the following gear:
Mac Studio M1 Max (not Ultra) with a 10-core CPU, 24-core GPU, 64 GB memory, 1 TB SSD storage
BenQ SW321C PhotoVue display
My reasoning is that I don't need more than a 10-core CPU since my sense is with Photoshop the incremental improvement from 10- to 20-core CPU and/or 16- to 32-core GPU is not great enough to warrant the additional cost of at least $1,400. The 2 TB SSD drive would be nice, but I can move images to an external drive if I need more than 1 TB of storage space.
I've agonized over the display decision for days, but the BenQ seems to be the best display under $2,000.
I'd be grateful for any comments on these choices. Thanks, Steve
