He came from a 3080ti so was worth it for him to double up his VRAM and get a uplift in performance.
Others can keep crying why 10GB was a great deal at £650 for a 3080 (but didn't realise their next 80 class update with 16GB will cost them £1200)..
but 3080 10GB really cost a lot more for people that didn't get the FE when they dropped in Unicorn poop amounts as many saw. Then the comedy of pre-orders being cancelled because the retailers didn't want to sell them at the price they sold them at and wanted to sell them at the new rates.. The whole 3080 thing and 3000 series thing was all comical and the 4000 series has added more insult to it all now. Didn't people get the hint when the 3080 12GB came out really at £1000 and the 3080ti 12GB was £1200 ?.. Did they really think the 4080 was going to be £650 again ? No chance the 3080 10GB only came to be thanks to AMD and the 6800xt performance and price... Don't forget that.
3090 was a great deal at the MSRP as we have seen now with the 4000 series and the cut down 4090 that is nothing more than a gaming card now and not a pro card with NVLINK and the insult with the 4090 is it didn't even have more VRAM so you could say well NVLINK dropped will make up for that, but all they did was sell a more cut down card for more..
All upset they didn't get a 3090 at the time or didn't see the point of the 24GB VRAM and thought 10GB would be enough for 4K were only fooling themselves that's why people spoke up and said the 3080 wasn't a great deal in the long term and well here we are proved right because people now are frowning even at 12GB cards and wanting higher VRAM than even 12GB too, rightfully so with the price premiums being charged for the 4000 series..
Nvidia sees that and has said ok want more than 12GB for 4000 series get a 4090 24GB,4080 16GB or a 4060ti with 16GB if you want to keep it for more than a year trouble free with new games clearly showing 12GB is not enough now too for 4K and in some cases even 1080P which is comical.
It's 2023 and Nvidia is telling customers that 1080P is the new thing... when 8K is around the corner... and 4K has been the standard for consoles the last 2 generations and TV's and monitors with 4k and higher are here and more coming with 8K and half 8K ultrawides. Nvidia has lost the plot really and is not just stagnating the market but sending it back to the early 2000's first 4K TV was 2003... 20 years ago and first 4k monitor 2001 22 years ago.. But now 1080P is the new big thing with GPU abilities with VRAM and performance on the mainstream cards.. want 4K spend £1600+ ..
Where we should be on mainstream cards easily doing 4K at sensible prices. But 8K TVs will be the norm in next few years and as we saw with 1080p tvs they were dropped the minute 4K came out and same will happen when 8K TVs come out in numbers.. 4K screens will go the way of the Dodo too.. and Nvidia will charge £2000+ for gpus then to run 8K for sure.. or by then they may have gone the way of the Saga.....remember Saga ? they controlled over 55% of the gaming consoles... then Sony killed them and MS XBOX... they became history overnight and a software company only again. Even Nintendo are nothing more than handheld consoles now.. Nvidia clearly doesn't see how they are damaging their market and how quickly history has shown the market can change and be controlled by new companies. Honestly I wish them the best as they are in the hands of a narcissist running the company and he's got a lot worse over the years.
