If he downloads a lot of movies that might get annoying, but if he's just streaming them from a Netflix app or something that's totally doable.
If he plays fallout idk how demanding that is to your disk, but games in general profit from faster storage. Movies usually don't as much.
If he plays a lot of AAA games that are bigger, his drive will get crowded real quick with 256gb. If it's just a few fallout games, he will be fine I think.
That said, 256gb is on the lower end of modern notebook hardware FYI, even on SSDs.
Asus sounds good.
Also heard and have seen it from HP work notebooks, wouldn't wanna buy them now.
Also older Acer or Lenovo laptops used to have a bunch of bloatware on there. Idk if that changed significantly. I do have to say, think pads haven't let me down though.
