A100 costs 10-12k USD 40GB/80GB vram and it's not even targeted at the individual gamer (not effective at gaming) -- they don't even give these things to big YouTube reviewers(LTT). So 4k people will be hard to find. 3090, you can find, that's a 24GB vram card. But that's expensive too and it's a power guzzler compared to the A100 series.
