I also feel like graphics cards are one of those weird things that command a lot of brand loyalty, so it's probably going to take more than near-performance-parity to move the needle.
Because AMD is a minority and game developers know it, driver-related bugs that would be priority 1 to fix if it affected nVidia users are bottom priority for AMD users. The AMD midrange cards are wonderful in terms of the hardware for certain displays and competitive in every way from a hardware perspective. Especially if you are looking for 60fps+ @ 1080p you can get awesome deals by going with AMD.
Just be prepared to occasionally have issues like BSODing whenever a game renders a lot of white textures like snow scenes for six months at a time unless you downgrade the drivers to a specific version, which will then be fixed in a driver update and broken again if you are an AMD user. Or to occasionally have driver crashes that developers acknowledge and don't fix for months. And to fuss with shader cache settings and things like that because those settings are busted for AMD for some specific game you want to play.
It's not even necessarily that the drivers suck. They don't suck. They're fine. It's that the developers don't have a big incentive to fix bugs that only impact a smaller segment of the market. While it's not like there aren't a lot of nVidia only bugs that crop up, because of its market share, those bugs are almost always a higher priority to fix and you really notice it if you have used both GPU manufacturers at the same time over a period of years or have used both at various times.
Most of the nVidia tech gimmicks usually suck and are uninteresting (HairWorks, physx, realtime ray tracing) and those that don't suck are usually matched quickly (Gsync). But the marketshare alone is sort of a perversely positive feature because it just means you are on the same drivers as the majority of the market so bugs that impact you are a higher priority for developers to fix.
Power usage.
This isn't even a gimmick though. This is the future, because our current way of doing shadows and lights will keep increasing in complexity, but will never be good enough. Whether nvidia's solution will work is a different matter, but this most certainly is not a gimmick.
Over the next 3 years and the next generation of cards, absolutely, great technology.
I can even link you to a video from a Youtuber sponsored by nVidia that essentially says that it is a nice-looking gimmick that will be nice for cinematic single player games that isn't that useful for fast paced multiplayer games in which most gamers will pick performance over image quality most of the time. DLSS because it is a performance feature is in a different category. Like Hairworks RTX is a tech demo type feature that most users will turn off to get dozens of FPS more.
The case is im not that picky when it comes for graphics. Ive seen too many games with wonderfull graphics and just plain boring.
