Re: How can I upgrade my computer for better performance & graphics in Sims 4?
@simsical-musical Desktop hardware is stronger than laptop hardware, including graphics cards with the same name. Having said that, you should still get good performance overall with your current hardware. If you'd like to troubleshoot the laptop, please let me know what issues you're seeing. Run a dxdiag and attach it to a post as well.

Your laptop can't be upgraded beyond the RAM and hard drive. Adding more memory may help if you're maxing out RAM as it is, but that's worth checking before you spend any money: open the Task Manager while you play and see how much memory the game and system are using. The monitor you use won't help unless the issue is the laptop's screen.
Desktops are better for gaming because, aside from their stronger hardware, they (should) have much better cooling. Plus, you can maintain and upgrade them more easily. In U.S. dollars, suitable gaming desktops can be as low as $700, a good monitor might be $120, and a quality keyboard and mouse might be another $120 total, less if you just want something that works.
An Nvidia 1650 Super should always run Sims 4 on ultra graphics settings, with a 1660 of some kind being a bit of overkill but perhaps still beneficial. Anything faster would be wasted on Sims 4 unless you wanted to play with high framerates (>100 fps) or at a higher resolution than 1920x1080.
The processors that come in prebuilt gaming systems should all be fine, although I'd avoid certain lower end CPUs for futureproofing reasons. Any i5, or any Ryzen 5 third-generation or newer, should always be more than fine. If you're getting a prebuilt system, you don't have a lot of choice in motherboard; if you're doing a custom build, that's a much longer conversation.
Feel free to keep asking questions.
