That's a good choice for Sims 3, able to run all packs together on ultra settings with a bit of room to spare, meaning even a lot of custom content shouldn't drag down performance much if at all. (The game itself has limitations, but I'm sure you know that.) It's a good price too, about the same as other laptops with similar hardware.
Are you ready to buy now? Because there are always good options in this price range, but prices do fluctuate for a given model, sometimes dramatically. So there's not much point in picking out a specific model until you're ready to order.
If you are looking now, this is the same laptop, except with twice the storage, and £20 cheaper:

These are other laptops with the same configuration as the one you're considering, except that the second and third have a slightly stronger processor. They're all £750.

That's just one site; others will have more options in around the same price range. The point is, you should always be able to find something, but it might not be the same thing you currently have in mind. And if you don't like your options, wait a week and look again.
