i go there.

False, RX 570 User here, 0 problems in 5 years and counting... A friend of mine had an GTX 1060 for 2 years and now it is showing artifacts. I think it depends on the temp and the care. My friend is constantly reaching 80°C meanwhile I don't let it reach the 65°C, changing thermal paste every 6 months. But is true my last AMD card that was kind of problematic was the R7 250, a lot of problems and ended up showing artifacts and dying.

u could pay 200$ for a 6600, or pay 350$ for a 3050 and like 20% or worse performance across the board. amd gpus are great

I dont think a subreddit would be the best place to determine whether a gpu, much less a company's gpus, would all have issues, considering the only ones that are posting are the ones experiencing the problems. however, you are right that certain games favor nvidia gpus (but it goes the other way around), applications tend to work better on nvidia gpus, nvidia gpus tend to have more features like ray tracing cores or dlss, and nvidia tend to hv more refined drivers. The good thing with amd is that it is open sourced, so I can enjoy it with linux support with no issues while I have to go through a few more hurdles with nvidia (not much of a reason, but a big one for me), tend to be cheaper with the same amount of raw performance without the fancy features, and amd gpus tend to age a bit better than nvidia gpus. for instance, the vega 56 was slower than the 1070 at launch, but with consistent driver updates that fixed amd's initial unstable drivers, it is faster than the 1070 (even without flashing the bios).

i dont mind mining gpus, thats my second one i buy and its fine. I had a probably from mining rx580 and sold it when it was 3x the price i bought lol.

The chip itself isnt new, the board is.
