I'm sure it's sufficient in a pinch but if you're considering one with the specific purpose of being a laptop it's probably better to just get an actual laptop
there already is a project for x86 to ARM translation on Linux called box86, and there's another one for x86_64 called box64
havent heard about them in a while but I remember seeing a video of someone playing doom 3 on a raspberry pi with it so it seems very promising
it probably is
I haven't seen one for Ghost Trick: Phantom Detective either and that also has Denuvo, so I have to play the switch version in Ryujinx instead
