You are very wrong. I sold a 3090 for 1000 bucks before getting 4090, about 2 years later. Meanwhile AMD was selling 6900XT and 6950XTs for dirt cheap prices, making it impossible to sell the second hand AMD cards. The demand for my 3090 was crazy, meaning I put it at 800 dollars but ended up getting 1000, tons of people wanted my card. This is why demand matters.
Nvidia is clearly in more demand in the second hand market and prices go up. Think iPhone vs Android. Android phones are worth nothing when you are done with them, for the most part, since they drop in price alot of time. Same with AMD hardware, price is what AMD adjust. This is also what AMD is going now with entire 7000 series. They did it with 6000 series. This makes your old AMD GPU a hard sell and its 100% fact. Sold tons of hardware from both sides.
Upscaling but especially DLAA improves on native res every single time. Native is not even close in terms of IQ. DLAA is the best AA in the world right now. Regular AA is slowly dying and leaving new games, FSR, DLSS and XeSS is the only option in most of them and going forward, this will be the case for pretty much every game released.
Nvidia drivers are better for sure, this is commen knowledge and you can find tons of proof confirming this. Nvidias driver team is much bigger than AMDs. They support older GPUs for longer, in their recent driver they had a fix for 10 year old Maxwell series. When you leave the most popular games, play early access games or even using emulators, Nvidia is MUCH better overall. Support is next level here.
On the other side, AMD drops hardware support fast when they leave the arch (instead of doing refreshes of the same arch like they did many times earlier) ->

Remember Radeon VII? High-end GPU that went EoL after 4-6 months or so. Price plummet and MSRP was high to begin with. Proof found ->

While DLAA is the best for pure image quality, DLSS can easily improve on native as well, while also improving frames by 50-75% on Quality preset ->

Native looks worse, not better. Screenshots included here. Easy to see.
Pretty much all new games today have DLSS/DLAA or can be modded easily to do it. Nvidia uses dll files and you can easily change out versions, or mod them in. AMD on the other hand don't use dll files and you can't replace them. Starfield, the AMD sponsored game which did not have DLSS/DLAA on launch, got a DLSS/DLAA mod on day one that easily beat FSR. Techpowerup tested it, and this was their conclusion. My experience as well.
I already used RT and PT in tons of games. The future is now for RTX owners. AMD is several generations behind on this too. However, improving FSR and AFMF should be top priority for now.
In like 10 years, games won't even have fake lightning. RT will be needed, just like Metro Exocus EE, which won't run without RT support.
RT means developers don't have to waste time on lighting, GPU does it for you. Correct lightning and less work for devs. RT is here to stay and eventually it will become a must have.
AMD GPUs are cheaper for a reason, if they were actually better, they would be selling in much bigger numbers. They need to have aggressive pricing to even make people consider buying them and yet most people don't anyway. Why? Because they want great features, good support/drivers and overall better performance. This is not worth saving a few bucks for. The savings are wasted on power over time anyway, because AMD has worse performance per watt. And like I said earlier, when you actually sell the card later, you get way less money back from an AMD card. All this means that AMD GPU is not really cheaper. You pay less on initial buy maybe, but tocal cost of ownership is not really higher with Nvidia and you have less issues when you use it as well + better features.
