As of right now, Ethereum is just below $523, the lowest it has been in more than three months, and down more than 60% from its peak. As it drops in value, GPU prices are coming down, too. Right now, you can buy a GeForce GTX 1080 Ti for about $1000, a GeForce GTX 1080 for $600, a Radeon RX Vega 64 for $900, and a Radeon RX Vega 56 for $650. That's as compared to an MSRP of $700, $500, $500, and $400, respectively. The AMD cards still carry a higher premium over MSRP as they have for most of the last year because AMD's GPU architectures are more suited to mining than Nvidia's.
That's still a hefty price hike as compared to MSRP, of course. But it's movement in the right direction. Surely people will eventually figure out that mined cryptocurrencies don't benefit anyone but organized crime, miners who got in early and then got lucky, and the vendors who sell stuff to support the mining ecosystem. That's not a market that most rational people would want to enter. Once the bubble pops entirely, GPU prices can return to normal.
Of course, memory prices are still ridiculous. Way back in 2011, I saw a Black Friday sale of 16 GB of memory for $50. That was an exceptionally low price for its day, of course, and also during a period of very low memory prices that drove Elpida bankrupt and reduced the number of major memory vendors from four to three. But today, 16 GB starts at about $100 for DDR3 or $150 for DDR4.
