The past week saw a repeat of something that has been an ongoing problem for PC gamers looking to pick up a new graphics card: cryptocurrency profitability is way up, leading to shortages of popular graphics cards once more. We've talked about cryptocurrency mining quite a bit during the past year, and this latest surge in mining profitability is a bit hard to nail down. There are always new coins coming onto the crypto scene, but at least looking at WhatToMine doesn't indicate any major changes. Ethereum prices have breached $1,000 for the first time, however, and that might have been enough to drive further speculation on other cryptocurrencies.

Whatever the root cause, the impact on graphics card prices is clear: everything is going up. Again. Here's a quick rundown of the various popular GPUs, with MSRPs, November pricing (not including Black Friday / Cyber Monday discounts), and current pricing information. I've also included an estimate of mining profitability for the past 30 days, though the specific numbers are prone to debate depending on your source. For the "launch price," I've used the most recent official pricing from AMD/Nvidia, which means the GTX 1080 has dropped to $499 for the non-Founders Edition model.
