Need help for laptop specs

@amessysimmer  This last one should run the game on a mix of high and ultra graphics settings.  An Nvidia 1050 is significantly faster than a 950M, and until recently, it could run all packs together on ultra settings.  So if you don't have all the packs, you may still be able to play on ultra.  The only drawback of this laptop is its mechanical hard drive, but that just means slower loading; the game would run fine once loaded, and so would other apps.

In general, the more expansion packs you add, the more demanding Sims 4 becomes.  It's not linear though: the oldest three EPs are less demanding than the newer ones, and the load isn't always even.  For example, the effect of the Seasons pack depends in large part on the weather in-game.  Stuff packs are not demanding, and neither are most game packs, with the exception of Realm of Magic.  (I don't know about the Star Wars pack.)  Overall though, you can expect the EPs starting with Cats & Dogs to add a significant load, and everything else to have a smaller effect.

If you can get a laptop wtih an i5-8300H and an Nvidia 1050 though, you really don't have to worry too much, provided the laptop itself is in good condition.  This is the kind of laptop we'd been recommending to people on a budget until recently, when new models became hard to find as they were phased out in favor of the newer generation.
