What are you independently running? What are the limitations of your setup in practice, and what level of hardware is really needed in your opinion?
I'm disabled and need at laptop, - for reasons. Looking seriously at System76 options under $3k, so 6-8gbv RTX 4050 or 4060. I want to integrate SD into a Blender CAD workflow. Is this practical?
I know it's not Linux, but if you're looking for a Unix system, I've had good experience running SD on a M2 Max MacBook pro. It does ~1-2 iterations per second at 512 pixels.
