A used computer is a good choice. My current i7-4790 one cost me €300 a year ago, I auctioned the GTX970 for €80 and got a GTX980 for a little more from a friend. Runs AH (and PUBG) like a charm at 2560x1600/60Hz.
Blaming solely the bitmoney market isn't the only reason for high prices. There's a huge lack of semiconductors which is both directly and indirectly related to Covid19. Directly, the few factories on the market were affected for a while. Indirectly Covid is still the culprit: Due the restrictions people couldn't travel or go 'out' which saved them money which they want to save on entertainment electronics like PC's, game consoles, home theaters and whatnot. Working from home also raised the demand of better home computers and peripherals. The automobile industry needs a lot of semiconductors as well, a modern car has three times the code lines than an F-35 fighter!
