Does that apply to both Nvidia and AMD cards?

I had ~35k worth of video cards during my heyday mining, and in my experience Gigabyte and Asus cards have proven themselves to be the most hardy and resilient overall. Though do keep in mind that any product will fail if not maintained by the operator, doubly so when under high stress.
Again: Applicable to both Nvidia and AMD? I was under the impression that EVGA is the 'go-to' card for Nvidia and Sapphire is the 'equivalent' 'go-to' for AMD/Radeon cards. This is the first time I've read Asus and Gigabyte recommended - and does it matter what model or is certain ones?
I'm looking for a used card and wonder what to look for (I posted a separate thread on this). Also, how does one know if someone was properly mining their card.
I was wondering if someone has in their description 'modded bios to boost clock' whether that is normal or because the card was mined previously? Is it something to worry about? I read that mining cards aren't necessarily bad because often they undervolt the cards but there seems to be a difference of opinion - seems like 50% say 'don't worry' whereas the other half of people say to avoid mining cards.

In the long run a lower core clock, voltage and TDP are critical for making money, especially as ETH got harder to mine. Plus ETH wasn't super core intensive, it's actually hardest on the ram and the ram is likely to be the hardest component to break. Sure the fans are probably worn out but the same place makes all GPU fans so they should be easy to replace if you know the S/N (on the back of the fan).
I'd buy any working GPU if the price is right but for mining cards as long as they weren't abused I don't see an issue with paying normal used prices.
What's a scenario or example of a mining card being abused? What are signs to look for?
