I'd get a second hand one for 350 quid.
Getting a new one for 350 quid will net you a shit one which can't barely run games or whatever.
Any good one from 2013 or something would be properly.
Try n check refurb laptops or laptops that came from business offices.
They usually have good quality ones.
Then again, don't take me advice literally.
I'm not an expert on it.
