This is not entirely true, at least to my understanding. First, I am no fan of LHR on principle. That said, if LHR is effective, depends on what miner was used. While older miners were not able to bypass the LHR limitations, which meant for lower clocks/different settings when mining, I have heard that newer miners are capable of bypassing LHR with autotune, so that most cards are capable of nearly 99% optimum hashrate. There are a few cards where LHR is still not fully bypassed, the LHRv3 cards. (3080 12GB, 3050) These cards still can do about 90% of optimum hashrate via nicehash last I heard.Guys if your a gamer getting 2nd hand cards remember LHR is your friend...
LHR means the card was not able to run at full clock, or the LHR would kick in for ETH mining.
So they usually ran the card anywhere from 60-70%.
So in serious, all you need to do is pop the LHR and run furmark for 15 min as if the card has problems it will be on the memory side, and memory side artifacting happens right away.
Anyway, the big picture is, if you buy a used card, the thing to be concerned about generally will be the fans. Whether the card was used for mining, gaming, or both, or what have you, you don't know the environment it was in, how much dust/dirt etc. Also, the fans are mechanical parts, so often will be failing sooner.
