The 3090 is a pup - ludicrously over priced but only 8-10% faster in actual gaming benchmarks than the (very capable) 3080. All that video memory and nothing to use it for, as practically nobody is legitimately gaming at 8k any time soon - and those few that are even running PC games at 4k@60hz (rather than generally more useful 1440p@144hz) will be very well served by a "basic" 3080 - especially on titles with DLSS 2.1 turned on.
Combined with the fact that the drivers are intentionally hamstrung (SRV-IO disabled etc), artificially crippling performance in many of the high end productivity use cases that could benefit from 24GB of fast VRAM, I fail to see who the market is for these cards. It's got to be very niche, and/or full of morons.
Paying over the odds for any of these cards is a mugs game. Supply will catch up with demand in relatively short order - and there are some ludicrous deals to be had on cut price NOS or gently used 2080ti's right now if you're really desperate for something - as they were never cost effective for Crypto mining (unlike the flood of run-ragged 1080ti's that hit the market a while back).
Couple that with AMD chucking out something later in October that might compete or at least put pressure on the midrange market, and you'd have to be mental to throw more than RRP at a 30xx card right now.
