Seen a 3090 on eBay, bidding is at $11k. Only promises to ship when released
I can definitely see why people want the RTX 3090, it's a pretty good GPU... but I don't think there is any way people could do the cost/benefit analysis and decide that $11k is the right price to pay.
This mainly applies to people who need to run GPU nearly all the time, not just a couple of hours per day.

And of course you can't play ultra high end game settings on the cloud.
No matter how you slice it, this one "fell off the truck" somewhere, it's an unreleased product, you're not supposed to have it yet.
