However I read that the interest of nvidia is to sell a lot of 10xx when Turing will arrive because the stocks are still important
True enough, but as time marches on production of the new cards will start to increase inventories and motivate them to clean out the old stuff and move to the new stock to facilitate free cash flow. The question hard to answer is if that will be Q4 this yr or Q1 next.
Whenever that occurs should push 10XX series prices down.
