Hear this every time, and I think people who love AMD live in a pro-AMD echo chamber where they do no wrong.
-There are driver issues, it is not unusual for a new AMD card to have both playability and performance issues for the first year. This normally goes hand in hand with the people who say "but this time I'll try AMD", own the card for six months, praise it in all the forums to much back slapping, but keep quiet about the really annoying issues it has, eventually get sick of the problems and go back to Nvidia swearing never again. Nvidia cards tend to come out the gate with better stability and performance, fine wine is not really a good thing, it just shows how long AMD take to make stuff work properly.
-There are stock issues, often you simply can't buy the AMD cards, where as Nvidia has better availability. Again everyone with selective memory forgets this - e.g. the 6xxx series was mostly unavailable for the first year or so, sure Nvidia wasn't easy to get either but the steam sales show it was a lot easier to buy an Nvidia card.
-The price for most of the cards is not that cheap. Sure AMD tend to do a fake RRP and sell a few cards at that price when they release (mostly to the AMD red fan thing whatever it was called so they praise it on the forums), late in the life of the card they get cheap, and sure a few people have got great bargains, but most people when they take a look can't find those amazing prices anywhere.
-Lack of features do matter, no matter how many times people say DLSS is fake trash (now replaced with it's fine but use FSR now AMD has that) or ray tracing won't be worth it for 5 years whatever it's just not true. People want the features they see used in the AAA games, and Nvidia make sure the AAA games support RT and DLSS.
-Even if Nvdia is evil nobody cares. All AMD fans just don't understand how you can buy a card from such a nasty company, you've gotta support the underdog (which is really the basis for this thread). Most people just don't care when it comes to their money, including a lot of AMD fans who will recommend AMD to everyone in every thread, but when it comes to spending their money quietly buy Nvidia.
