The memory shortage is specifically linked to DDR6, which doesn't relate to the 32 gig you recently bought. This is the main reason for the short supply on new cards, and why NVidia also have stripped back how much is going to be on 3080 cards from there original design intention. The difference between 10 gig onboard vs 24 gig on board (plus better bandwidth) is a major plus for the 3090. Indeed a 3080 has less on board RAM than my current 2080 Ti, and is one of the main reasons why I'm not particularly considering it as increasing the supersampling ratio in VR eats VRAM, plus real world performance comparisons show a 17% performance increase with the 3080, vs 33% vs the 3090 over my 2080Ti, which isn't enough to warrant it imo for me, and I'm sure that it won't be enough for what I want to do personally re Reverb2. If it wasn't for VR I wouldn't even be considering an upgrade as my 2080Ti runs everything in 4K maxed out (nearly in DCS but everything else anyway) already.
Ultimately, what a user is prepared to pay, comes down to there own disposable finances at that time, and why they want it, the same argument could be levelled at someone who buys a Ferrari as opposed to a Ford Focus, or indeed a cheap second hand car.....
As to getting a 3080 for less than 1000 in the near future (within a year anyway), good luck with that, I hope you will be proved correct, but I sincerely doubt it. Of course we could all wait 3 years and buy a 4070, which will no doubt be better than a 3080 and a lot cheaper, tis the way of things....
