zoraaa14 You don't need to spend nearly that much for a great computer for Sims 4. Even $2,000 including the monitor is more than the game can reasonably use. But if you want something more powerful than what's necessary for high-end settings, let me know.
As a baseline, this is overkill for Sims 4 in terms of its processor and graphics card, and it also comes with more storage than you'd ever need. The game couldn't use anywhere near all this power, at least in its current state.

This one has a faster processor and graphics card:

This is not to say that these are the absolute best choices for you, only to give you an idea of what's out there for a lot less than you're willing
For the monitor, do you know what size you want? The sweet spot in general is 27", but some people want larger screens, or an ultrawide screen, and some don't have the space for even a 27" model.
