I'd been planning to upgrade my desktop as a christmas present for myself.

Now I have the cash and was looking at buying my PCPartPicker list, the cost of the 64GB DDR5-6000 RAM I planned to buy has gone from £300-400 to £700-800+, a difference of almost the price of the 9070 XT I just bought to go in the computer.

I guess I'll stick with my outdated AM4/X370 setup and make the best of the GPU upgrade until RAM prices stop being a complete joke.

Manufactures aren't dumb, they lost a lot of money in the last cycle and aren't playing that game anymore. No additional capacity is planned, OEMs are simply redirecting existing capacity towards high-margin products (HBM), instead of chasing fragile demand.
