These are decent GPUs for anything other than heavy gaming. I'm driving two 4k screens with it, and even for some light gaming (such as factorio) it's completely fine.
I'm under the impression that Factorio can run on any GPU capable of producing video output at all. years ago when I played it, it ran perfectly fine on whatever iGPU my 4790K had. 60 FPS/UPS with pretty big bases (although iirc I did disable all video effects like smoke to avoid cluttering the screen)
I agree, my 780m is quite capable in most games. Depending on the resolution & settings even cyberpunk 2077 is playable at 60fps. MS Flight sim though hits (presumably the memory bandwidth bottleneck) hard.
