You are probably young and you apparently have a lot to learn. You presume, that if someone doesn't have whatever hardware, he is poor. In some cases this is of course true, but in most cases people don't buy such hardware, because it's simply nonsense in practical terms. I have been building machines probably before you were even born so I know very well what I am talking about.
Nvidia these days only competes with itself and high-end GPU with 16GB Vram for the given price is a moral crime. Not that it matters so much, games aren't really being made anymore. Plus, you have to wait few months before it is even remotely playbale as it's often full of game breaking issues. Mostly just GBs of content with no substance really.
And so along with the whole x86 world, Nvidia will fade away too. And it will be good when it happens.
