Come on... The Strix LC 4090 was $2500 at release. Its a $500 increase. I paid $2000 at release for my Strix 4090 at MC. You're exaggerating massively and not comparing apples to apples. I don't know what your "top shelf parts" were, but the 4090 was simply NEVER so much cheaper than the 5090, nor honestly was it ever really that available, that this line of reasoning makes sense. You built your system far into its lifespan, near the end of it, and for sure did NOT buy an Asus LC card. Complain about the 5090 in 2 years.
This is similar to how people pine for "the good old days when GPUs were cheap", yet seem unaware that 20 years ago the relatively anemic 7800GTX was $600 which, adjusted for inflation, was a grand. Hell, in 1990 I paid $500 for a PoS ATI VGA Wonder. That was $1200 in today's money for a card that did basically nothing by today's standards. This has ALWAYS been an expensive hobby and PC parts are actually cheaper than ever. No one needs the 5k series. You can pretty much simulate reality on a 4070 ffs.
The only real issue I see is scalpers, but that's OUR fault as buyers who can't fight their addiction. Were scalping of PC components possible back in the day, it for sure would have happened. After all, even back then it was already common for event tickets.
People need to learn to just ignore any new parts release for at least a year and let the scalpers go underwater, but people never learn. The 5090 is the most ridiculous thing yet BECAUSE it's such an incremental improvement, and yet people are still losing their minds.
