idk, i disagree. I do quite a bit of stuff on my workstation, including some video editing. And the only real upgrade i would make to it right now is going to 30 series nvidia, or the AMD equivalent, because linux. And ryzen 5000, because it's just such a good die process.

Neither of those are new. You could easily buy used hardware in both of those brackets. My current workstation is running a 1070 and an r5 2600. Ancient hardware by todays standards, but perfectly serviceable. Maybe in a laptop? But even then, i have 12 year old laptops, they run fine. They do what i need them to do. And they look great.

You have any specific examples? Phones maybe, they have such a short life cycle it's not hard to find 2-3 year old flagship selling at a reduced cost these days. I genuinely can't think of any examples where this wouldn't happen.
