I'm not moving past my DDR4 build (and the 32 GB of DDR4 2133 MHz backup chips I still have around from way back, before I got the current 3200 MHz ones) until the prices go back to being at least partially sane. This also means that CPU manufacturers are not getting my money (since the 5800X is fine for now) and I have no reason to get a new GPU either (though admittedly the B580 isn't perfect).
What if this is the lowest that prices will ever be?
As Yogi Berra famously said, "It's tough to make predictions, especially about the future." But based on historical tech industry trends, a price increase in one component that's this rapid and extreme, is likely to eventually regress somewhat toward the long-term trend line - even if that trend line experiences a longer-term shift upward.
As always, some interpret certain recent events as reason to conclude "but this time it's different." Occasionally they are correct. But that doesn't change the fact that it's reasonable to assume some of the recent extreme, rapid price inflation is due to shorter term market distortion. It's also pretty clear that some of the recent increase in demand represents a stable increase in the long-term trendline. The question is how much is long-term stable and how much is short-term distortion.
Then I will make my build last as long as it can, in protest of that. I do expect at least a performative price drop in the coming years, though.
