I'm not refering to just the 4090. The 4090 is cool and a performance badass, I won't knock it on that front. And, like you said, it is a premium product. However, it's not just the 4090. if the 4070(4080 12gb) costs $900, what is the 4060 going to cost? Are we going to have "mid ranged" cards that cost $500?
There is a lot more going on than just rich people paying for rich people graphics cards. I can afford a 4090, that doesn't mean I think that the VALUE of a 4090 is there to justify the cost.
When you get to a point where you have money you have to look at expensive purchases and think, "is the value here to justify buying this." I cannot justify the cost of a 4090. I would like to add that cards in the $500 price range are not midranged. I'm sure the 4060 will be a powerhouse, but I also think, that the 4060 in no way will be a midranged card. People can hide behind inflation or better performance numbers all they way, it's not going to be a midranged card. They are inflating GPU prices.
I'm also willing to look at this from a business perspective, their costs HAVE gone up. but hiding behind raising prices as a justification to inflate their own prices is just wrong. We, as consumers, should not stand for this.
