My 990pro 2TB that I paid £80 for in December last year is nearly £200 now.
Call me an optimist though, but I do think the prices will settle. I don't think they will go back to historic lows, but I think they will settle to something more reasonable. I think a lot now is panic buying and squeezing as much as they can. I don't believe 2028 either until it improves.
"Sources", call me a conspiracy nut, but I bet those "sources" are the ram manufacturers, of course they are going to say "buy buy buy" prices will only go up. Since covid I don't trust any of them, I'm sure we all remember "it's shipping, it's X or Y", we aren't bending you over, but magically shipping prices only effected GPUs, stuff like motherboards, no increase. Then I think Zotac had a statement (might have been someone else) with crocodile tears about how they are trying to get cards to gamers, but Zotac were selling direct to mining farms.
I wouldn't trust a single thing any of them say.
