Hard pass on the Kingpin this time (and in the future) after 2080Ti KP's lost almost all of their value within roughly 15-16 months after launch. They just won't sell anymore unless for 30% of the price.
Looks like the meta would be to buy the absolute cheapest model of the 3090 or buy an FE and add an AiO/WB, these seem to retain the most value.
