Hopefully everyone looses confidence in mining and I can start buying cheap used GPUs.

Is it a good idea to buy GPU from mining farm? Surely it was overclocked and in bad thermal condition, so it could barely survive. I think, electronic circuits degrade in those circumstances, so this GPU won't last long.

a lot of ETH miners underclock and undervolt the cards.

For now it's just a rather small correction, keeping in mind how much they had gone up in the last 60 months. On the other hand, the uncertainty with Bitcoin's Segwit activation, possible chain split etc won't help in the next few weeks including August. It could make the bubble pop... or not. What's weird is that coins that have already adopted SegWit, like Litecoin, seem to suffer even more than BTC during the dips…

I can see that almost 50% of blocks are generated with SegWit support. In a few weeks it'll be more than 50%, unless trend drastically changes. Does it mean, that SegWit won and Bitcoin is safe?

gpu mining becoming not profitable will not only flood the market with cheaper used gpus but also reduce the excessive demand for new gpus, both will lower prices.

Mining is about flop/$, rather than flop/s, so overclocking is actually rare. The best mining GPUs are the ones that are most efficient, not most powerful; overclocking usually trades efficiency for power.

Most GPU manufacturers allow RMAs to carry between card holders. If you own the card you can RMA it. Out of 1/10th the cost of the GPU, some paper work, and some time waiting for a package in the mail, you get a brand-new-old GPU!

I'd love to upgrade from my GTX 750 ti (that I picked up for 60$ and an order of Chicken Tenders & French Fries) to something more high-performance.

Also, if you're not doing a 100% duty cycle, and replace the thermal compound on the card, even a well used card will last a few more years. If you can pick up the cards as sub-$70 it's still worth it.

I have mined, and know people who mine, and so while it might sound counter intuitive, have never heard of a card going bust.

The only card I did hear of was a gamer who didn't mine, and as other comment mentioned, it was RMA'd.

I ran a R9 380 at 80 degress for months >_< sold it but it still worked a treat.
