It is a rumour of the greatest degree, but chatter on the web at this moment is that the release pending GeForce RTX 3090 would/could cost you roughly 2000 USD. 

ChipHell user Alienxzy posted a screenshot taken from an insider account (alledged) with information regarding plans for next-gen RTX 3090. The partner in dispute here would be Colorful, and there is validity there as the guy posted a screenshot. Colorful would be releasing two high-end versions of the RTX 3090 graphics card, a Vulcan (air-cooled) and then a Neptune (hybrid liquid-cooled). Prices would sit at CNY 14,999 and 15,999 respectively (yes in that order), that's about $2000 for the Vulcan X OC and weirdly enough the Liquid cooled version would be a notch cheaper.

We'd advise you to be very careful with this info as this one definitely is not confirmed.  The graphics card photos below are for reference only, these are the RTX 2000 series models, carrying the same name.
