Personally I won't applaud Nvidia until they do the following:
4080 16GB $800 or less
4070 12GB $550 or less
The performance uplift otherwise makes zero sense because yes you are getting an uplift... For a shat price. The 4090 price is easier to swallow because of it's target audience who are the Halo card buyers. But the 80 series shouldn't be in the Halo card price range.
