You are getting more computer for your money. And only a tiny niche of collectors are foolish enough to waste a lot of money on old video games. You can find the same hobbyist collectors for anything: figurines, model trains, coins, etc. Collectors are economically meaningless.
The question is not: "are you getting more computer for your money?"
The question is: "are you getting (anywhere near) a linear scaling of computer for your money?"
Because to me the answer to the second question is a resounding "no" and the strongest evidence of that is all the people walking around with high-end iPhones who can barely afford rent on tiny single-bedroom apartments.
