I can neither confirm or deny I’m a similar age to you but I’m also not interested at all but I think it’s more down to the state of games these days than the price.
Hardly used my 3090 and I’m going to keep it for years at this rate. Prices are silly though.
I like to think my gaming time has decreased because of the above and not my age
Regardless of price, gpu upgrades each gen have definitely lost the magic over the years for me. Sad, but expected, diminishing returns. Sort of like taking steps to turning a square into a circle by doubling the sides. The first step being the most dramatic.
In the early days, upgrades were great in all aspects, and new features that made an obvious visual change were common. We lost crt's
To mind, tessellation was one of the last stand out features. PhysX fizzled out, 3d vision too. Modern gfx are great, but visuals each gen aren't much different from the last, seemed to get stagnant, turning into fps and resolution chasing (the fps chasing being a result of poor motion handling with flat panels, 120fps is much more important on an lcd). Ray tracing is exciting now though, so got me back into gfx chasing. Just wish there were more games utilizing it.
Will I upgrade to 4090? Very likely, but I'm under no illusion and fully expect it to be my most lacklustre upgrade to date.
