“Powerful enough for productivity tasks” is very variable depending on what you need to be productive in. Office sure. 3D modelling? CAD? Video editing? Ehhhhh not so sure.
I don’t know enough about CAD to comment but video editing is considerably more expensive now for a bunch of reasons and I don’t think an Amiga could handle it now.
Video compression is a lot more computationally complex now than it was in the 90s, and it is unlikely that an Amiga with a 68k or old PowerPC would be able to handle 4k video with H265 or ProRes. Even if you had specialized hardware to decode it, I’m not 100% sure that an Amiga has enough memory to hold a single decompressed frame to edit against.
Don’t get me wrong, Video Toaster is super awesome, but I don’t think it’s up to modern tasks.
