It’s fine to offer a product at the top of the line. Nvidia was trying to push prices up for their entire product line, and the market responded and said “no thanks”. They need to adjust accordingly. The top of the line needs to cost around seven hundred bucks, and each generation needs to offer real performance gains to get people to upgrade.
Apple did the same thing with the $1100 iPhone XS Max, and the market responded in the same way. It’s too much money for a phone.
