I'm a product exec now but used to be designer and lead UX teams. Even though I don't use those skills as much nowadays it's still a almost daily hobby of mine.
Like the rest of HN (maybe it's HN's fault!) I managed to convince myself that I not only needed a Mac Mini desktop but also a 4090 rig for AI.
The 4090 hasn't been booted up in 9 months and the Mac Mini is now the world's most amazing 10GBE NAS server. My older M1 Max Macbook Pro and underpowered newer Macbook Air are the only things I use.
I mean, I'll take the 4090 if you don't want it :)
It's funny how we convince ourselves we need things. I bought myself a 3080 Ti a few years ago because I wanted a gaming computer, but then I ended up buying a Playstation 5 and not using my computer for anything more intensive than Factorio. More recently though I have been using my 3080 for Comfy UI image generation and messing around with local models, so I guess it's getting use now.
I think you’re using “underpowered” wrong here.
