If you're talking about the graphics cards after pascal and vega, then probably not, as windows 7 support will end in a few years, and windows 10 has dx12, and maybe even dx13 in the future.
IDK. Win7 like XP has/had a huge following. I could see a basic driver being released for it. But I doubt it will get monthly updates, etc. If drivers came from MS it would be gone already.
