He also said not to buy used because it might be a mining card and you'll have vram problems. Go buy a new card now because the price dropped. No Thanks, they still cost too much especially on the low to mid tier. Should be under MSRP for a 2 year old card and a new gen coming.
Jay really comes across as a shill for the industry in this video. Any reasonable person would admit that any advice they give right now is at best a guess, but Jay actually calls people idiots for not trusting his guesses.
It's just a simple fact that we are not even at the same level of price/performance we were before the crisis (remember that the original MSRP of the 3080 was $699), let alone at an exceptional price/performance level. And as you say, at this point in the lifecycle the prices should be reduced anyway.
In general, I have a pretty low opinion of Jay's ability to even judge what is good price/performance. His channel revolves around unnecessary complexity because it is cool. Even for his 11 old daughter who plays the least demanding games, he build a PC with 600 dollar motherboard, an i7 10700 and a 2080 Ti, with custom watercooling for both the GPU and CPU. And that entire build was sponsored anyway, so he got the components for free and never had to make any hard choices.
So for Jay, a 3090 Ti is great value, because it costs him $0. And a 3070 Ti is great value, because it costs him $0 to get one.
You should watch channels like Hardware Unboxed if you want real info on what is good value. Jay is like Linus, very entertaining, but bad at giving good advice and heavily corrupted by the industry.
