That would work very well for Sims 3. The only point that could be improved is the HDD, on which both the game itself and things like CAS and Build/Buy will load much more slowly than if it were installed on a solid state drive. TS3 will run the same once it's loaded though.
Sims 4 isn't nearly as affected by the speed of the hard drive. An Nvidia 1650 will run all packs on ultra settings right now, and quite possibly for the entire development of the game (it's difficult to say for sure given that we don't know what future packs will look like). However, if you like using a lot of "high poly," as in high-resolution, custom content, you might benefit from a slightly stronger card either now or in the future
If you're interested in seeing other options, feel free to ask; just list your budget and country, as well as any other details that matter to you, like having a lot of storage or running other apps besides the games.
