There's a virtual ocean of laptops in that price range, so besides the programs that you listed, is there anything else specific that you can given information about? Brand preferences, features, etc?
If you're literally just looking for any capable laptop, look at the system requirements for Sims 4, and make sure you are within the recommended specifications when choosing a laptop, and go for a best seller while paying attention to reviews. Amazon would be a good place to start, although I don't know of any popular sites for the UK when buying laptops.
I just want the most specifications out of the price. Windows ten would be handy however touchscreen doesn't matter. Mostly just processing power is important. I just want a speedy laptop for the best price possible.
