You will shut up and accept it, because you have no other choice.
Graphics cards possess immense processing power for the money, and it was inevitable they would inflate in price once applications started to make good use of their processing power. Nvidia has been trying to increase GPU prices for years simply because they are sick and tired of selling a 1080 for $500 when the professional version is being sold for $2000!
AMD didn't have the mindshare to demand higher prices, but now their cards are also finally being utilized for business purposes.
Quadro price are justified for the added value that they bring for people making a living from content creation or scientific usage.
Geforce and radeon are mainly entertainement tool that can also be used for compute. Gaming card can do compute task just fine, but the developement of their driver isn't made with optimisation for the lastest rendering engine, or the lastest 3d software, it's focalised on games. You want a quick fix for a bug in maya ? You gotta buy a quadro or a radeon pro.
Both Nvidia and AMD have compute unit that were made from the ground up for heavy processing 24/24 7/7 for several years. But the average joe don't buy them, he can't afford it. Instead he's buying stuff that was meant for entertainement. And the demamd is higher than what the factory can put out. Hell even without miners, we already had issue with stock because manufacturing silicon becomes harder and harder. Mining need to have specific hardware that is cheap to make and got a low energy cost.
I'm also doing video edititing 3d rendering/compositing with my pc. So I was really glad to see opencl, cuda, bring more speed for those kind of task.
But for me mining doesn't hold the same value. Mining isn't something that you can enjoy on the long term with a single gpu, the more people that get on the band wagon, the more power it require. Mining hunger is growing way faster than the technology it's using. ETH is the cause of unprecedented energy drain.
Good thing laptop are not concerned by all of this. If their price had to increase because of all this we would have reached total insanity.
