I try not to wait for those moments to arrive; instead, I sell off my graphics cards. While it is possible to run them at lower settings, there's already no profit to be made as it is, so using lower settings would just make mining completely unviable. If a graphics card can still pass gaming benchmarks, I sell it and purchase newer models.
Can confirm the VRAM thing, been through it.
I had 5 rigs with 6 RX470s each, same hardware everywhere, and still some were rock stable and others kept freezing.
Always figured one card or another had a problem... never found which one.
And yeah, when you've built and set up the rigs yourself it's better not to be too far away.
Basement is usually a good spot, the attic a lot less in my opinion.
Selling them while they still pass gaming benchmarks makes sense, that's probably how most of them end up with gamers anyway.
And it must be exactly the same with cards used for AI.
Since most of those will hit the second hand market one day, I think gamers are in for some nice crashes...

On the other hand, running older cheap hardware also saves you from big investments, with GPU prices being what they are right now.
I'm messing around with a local AI myself and struggling to upgrade it, hardware prices are crazy, even second hand.
