i think that even if the price/performance is right. The fact that we cant tune them like we did from the 6000 series back, they will still be very inefficient and no one will want to mine with them. If morepowertool works again, i might consider buying an AMD like i did before
When Ethereum was expensive and could be mined on video cards, miners bought laptops and game consoles and no one cared about price/quality. I think the only question here is the emergence of new coins for mining. While there are no coins for mining on video cards with a quick payback, the demand for video cards will be low.
