256GB. Do you need 512? 512 is still $1200. Performance wise this is a HUGE upgrade. Now the displays, I know some people like Apple displays as much as I hate them. Studio Display is way overpriced, option that I would consider with mate glass and height adjustable stand is $2300. 😱 And it’s still only 27”. I would suggest Benq PD322U, that’s the one I have for 2 years. It’s not as pretty but it’s much better for your eyes and colors are super precise. I also have a M1 Studio base model, M1/2 Max over M1/2 is not that much of a difference unless you do video editing and 3D rendering. Base M processors are beasts, just make sure you get enough RAM, don’t go below 16GB.
