Ok, I understand that NVidia does not want to mine themselves, but why on Earth won't they just raise the prices to the level miners are willing to pay?
"We want to sell to gamers, not miners" is the stupidest excuse ever. Isn't capitalism all about selling to the highest bidder? Why do they even care about who buys their product?
EDIT: Also, think about this: gamers that are considering upgrading their hardware get additional incentive - Etherum mining makes buying this new, shiny GPU basically free. Typically, after 9-12 months the initial investment is paid off. Without the possibility of mining many gamers will delay the decision about buying a new GPU, hurting NVidia sales further.
