Pro or Max chip?

Is there a threshold by which it is better to upgrade to a Max chip, rather than adding additional RAM to a Pro chip?

Can lower RAM on a Max chip perform better than greater RAM on a Pro chip?

A significant additional factor for me at least, is that I multi screen.

Usually at least 2 external screen plus laptop screen.

If possible another external screen either via display/usb (if compatible), or failing that HDMI out.

My current setup is a Samsung Odyssey G9 ultra wide (2 QHD screens), laptop screen, 4k 50” TV (for anything I want to view at extreme size, standing/sitting back, rather than close up use.

I also have Apple TV connected to other HDMI in on TV, so can watch other stuff if wanting a a break from work stuff).

I am assuming that to have any hope of running this screen setup with a MacBook, I will need the Max chip for this, if nothing else?

Unless there are any aftermarket hardware/software to enable additional screen?
