@chW33Nie There aren't a lot of really good options for $750 U.S. at the moment; it seems like most of the older inventory has turned over. But I did find a few laptops worth mentioning. These three have an RTX 3050, fast enough to run Sims 4, all packs included, on ultra graphics settings, with some room to spare. They also have 500 GB storage, which is convenient if not strictly required.

Among these, the HP is the best combination of quality and in-game performance, but they're all more than fine.
This model has a faster RTX 3060, but only 256 GB storage. That's still enough for Sims 4 but probably not for an additional large game unless you're careful about storage. Still, it's worth mentioning because of the significantly faster GPU, which may help down the road even if it's not necessary now.

If none of these are quite what you're looking for, let me know why, and I can take another look. There are definitely more options out there, particularly with a 3050 and a 256 GB drive, which I didn't mention because they weren't much cheaper and 500 GB is so convenient to have. But they're also viable options if the ones above don't fit your needs.
And if you have more questions in general, please feel free to ask.
