I'm on the same boat with a 4080, the extra GPU RAM of the 4090 over the 4080 would have been nice, but it still wouldn't be able to run any decent models.
I configured my PC in December 2023 with a kit of 2x32GB DDR5-6000 for €249, thinking I would upgrade that RAM later to 128GB by just adding another kit. Now nearly 3 years later that same kit is over €1500 :-(
I've also lost all interest in upgrading to a 50-series GPU. With exception of the ludicrously expensive 5090 the entire 50-series lineup is capped at 16GB, I don't see the benefit of upgrading.
Yea - (I wish I had gone with 64Gb ram...) there is no reasonable upgrade path for us beyond waiting, unless the 5090 comes down to MSRP, which is unlikely. The 4080 is still a nice GPU, but the 4090 would have been a better option, if we'd known what was coming!
