It may come across as hostile but so did the first reponse. I am not looking to justify the expenditure, I would much prefer saving the 1200 bucks but i can afford either luckily and want to be sure I am not giving up a substantial bit of performance for the money. Mainly battery life honestly I have heard the M1 Max struggles a bit there?
1)It will be a 16inch model, my current one is as well(wish it was a 14inch for when i travel I would then keep it as a travel laptop)
2) its a full M1 pro 10c/16gpu with 1TB SSD. Battery life on this machine is excellent no complaints. CPU and GPU performance are fine, they could be better especially CPU wise as i do not do a lot of GPU heavy things other than some video and photo editing on my Mac
3) I would like to be able to build test labs on the machine in EVE-NG for example if that becomes possible on the Apple Silicon chips in the future, I also want to be able to run windows in a VM when i need to. Also some linux VMs for testing of software
4) My PC is a Ryzen 7950x with 128GB of RAM. RTX 3090ti video card. It gets used mainly for editing videos, photos, some coding, work from home, and serving files to the rest of the house, and gaming on occasion. RAM usage can be anywhere from 16gb if just working from home, to well north of 70GB if using after effects for example.
I also have a Dell Precision 5820 at work with a Intel 10980xe in it and 64GB of RAM
