I think the flagship 4090 prices is OK compared to last gen. ~13% increase in a era of inflation for ~60% FPS 1440p and ~70% 4k according to an old Techpowerup review I just scanned. Perhaps more with the latests CPU's / platforms.
If we'd had that through the rest of the range ~15% price increase for 50-60% FPS increase at relevant resolutions (by tier) + more reasonable amounts of VRAM (12GB on 4060+ up, 16GB 4070+, 20GB 4080+ I'd be fine with it. The days of £200 mid range cards have long gone especially since Nvidia made the die much larger to add all the RTX fluff that we all have to pay for.
A 1060 6GB was £240 at launch, add in 40% inflation and 10% deterioration of exchage rate then it would cost ~£370 today. Cheapest 4060TI at OC is £380 so pretty much in the ball park. I'd match the cut down 1060 3GB with the base 4060.
On the cost of the 4090... if you get the use out of it, then £1600 at launch, £600+ sell through used 2 years later when you replace is £10/week, £40/month. Lots of people burning that sort of cash on Sky, Ultrafast broadband, Gym memberships they barely use, daily Costa, Mobile phone contracts with a 'Free phone', football, golf, beer, cars they barely drive 8,000 miles/year in an all the toys trim etc. The list is near endless so for the performance and uplift it provides, I can live with the price.
What I do strongly disagree with is the deliberate removal of value from the lower end where GPU's are basically the same price for the same performance and VRAM as 3 years ago. I don't have the link but I watched a youtube some time ago where they quoted Jenson saying that 'People pay $500 for a gaming console, a GPU is a gaming console in their PC so we'll target our average selling price at $500. That's exactly what they have done, all but the lowest tier cards are north of $500 while the cards below $500 are not much below the price point and fairly undesirable due to only really being for 1080p.
I'd want a 50%+ gen upgrade on my 3070 so that would be 4080 at 2.5x the MRSP. That's a big fat no... not only do I not game enough to warrant it, A 4080 / 4090 likely doesn't even fit in my case.
I usually skip a gen anyway but the 3070 was a bit of a stop gap in the GPU drought and It's a bit of a comprimise for VR.
Still at least the 50xx or 80xx will be an actual generational leap for a 200-250W card next time I get my pants pulled down.
