It varies quite a bit. I have an i5 with a 740M (2013) that is just barely supported. For reference that will run 360-era games fine given drivers. My 320M (2010) gets no love at all.

When you buy Nvidia for Linux, you’re buying obsolescence. It will work fine for a while and then they’ll hard-drop driver support at a certain kernel version. Your 3d acceleration will last as long as you can run an LTS kernel compatible with it. You may have moved on by then, but I currently have 3 Nvidia laptops that have between limited and zero 3D support in Linux. If I cared to run Windows or MacOS, 3D would still work. MacOS would also be outdated, though. In the future, I’m going AMD only.
