What Mav said. mid-range price laptops usually have a lot of the same stuff in them, the only thing you want to maybe consider is that you might want something better than just the on-board gfx card (which is often something like nvidias uhd 620 right now), anything above that, like the mx150 would be alright, in yours you have a 1050ti which is great. In a way you just want to check that the £900 doesn’t just go into other features and has only the mobo gfx card.
Then you might want to remember to, after you update the drivers for the nvidia card, to go into the nvidia control panel and find the setting that automatically chooses which gfx card to use. That’s because even if you do have a fancy card (like your ti1050) there is still a mobo gfx card, and the reason the setting exists is to save power and use the mobo card if you’re not doing ‘graphics heavy tasks’ then it automatically is supposed to switch to the ti1050 when you do - this feature (like most features in windows OS) works so-so, so whenever laptop power is not an issue you might want to set it to always use the ti1050 card if you’re doing editing, or at least take a few secs to google how this auto-select feature works with whatever software you’re using and what effects it actually has on power consumption.
