If you're doing it professionally, then that adds up.
This is such a ludicrous argument. If something is faster, it's faster. What's the problem?
if you're dealing with 45-61MP RAW files yes. More RAM and more GPU and CPU speed help. Of course.
I'm a photographer, and almost no one deals with 45-61MP RAW files. You're talking about a subsegment of photographers, subsegment of those who deal with making very large images, almost no one. It's your money lol, I just don't understand why you justifying so hard spending money on this incremental update.
I use 45MP RAW files from my Nikon Z7. Guess I'm almost no one. Thanks for the helpful comment. "lol"
