1080Ti was the top-of-the-line once released. It cost me ~$850 inc. 23% VAT, maybe 2 weeks after the premiere. Now for the same price, even with added inflation, you can buy a mid-shelf card.
Because of BTC mining, vendors noticed that people could pay much more, and prices, which were bumped 100-500% because of the BTC time shortage, remained at the 200%+ level after that. This is the regular price right now if we compare the same product shelves.
The whole RTX line, even including the inflation, is supposed to cost about 50-60% less. AMD is always adjusting its price/performance to Nvidia. They have a bit better prices, but still way too high to be reasonable. People simply buy whatever is available as prices won't be better anytime soon, but many buy budget cards as they can't afford anything better. We somehow laugh at the RTX4060/RX7600 8GB performance in AAA titles, but these cards sell the best. It's because of the stupid pricing.
Quadro is a different product line. It's not for gaming. Titan wasn't released for a long time, and it's an enthusiast gaming card. Like for "elite enthusiasts", not for mass sale. Nvidia also modified drivers some years ago. Everything that you could do on a regular GeForce could be done on Quadro with a proper driver. Now Quadro drivers are different, and to have the best performance in graphic designing software, you simply need a Quadro (even though looking at specs, it's slower than some gaming GPUs).
When they release a special version like Matrix, Lightning, KPE, or with a fancy liquid cooler, then it costs 20-100% more. Double-GPU cards were like 50%+ more, but we haven't seen those for a long time. However, check the new Matrix price right now. It's way beyond ridiculous for what it gives. I mean the user experience, not counting the fact you simply own one of those. XBOX or PS5 gives a better experience than a graphics card in their price ... and you still need other PC components. This is how stupid are the current graphics card prices. To enjoy the same, playing the same titles on consoles, you pay at least twice as much.
