Question Looking to buy a laptop.

She told me she'd like to play Sims 4 and Roadblocks on it.
I think you meant Roblox.

The cheapest laptop I can see off this site;
https://www.laptopsdirect.co.uk/ct/laptops-and-netbooks/laptops/gaming/under-1000?sortOrder=1
is the Medion E30e for £599 which is brand new.

Using this shortlist;

the Acer option for £529 seems like a good option

Specs wise it should have a lot of oomph for what your daughter wants to tax it with but looking into the future...I'd say you should up your budget and look into something a little more concurrent since the 12th Gen Intel processors are about 3 years old, while the RTX2050 is 2nd Generation RTX mobile GPU tech. We're currently on RTX5000 series, so that laptop will likely see support dwindling over time.

If the budget cannot go beyond the 400 mark, then the suggestions made above are worth a gander. You also forgot to mention the screen size which is why I didn't choose anything from that category while generating the shortlists. We have a templat;
that we ask users to follow in order for us to be well informed and provide the best possible suggestion.

My 2 cents.
