Re: PC recommendation to run the Sims 4
@EriSims974 None of these is a great option for Sims 4. They don't have a dedicated graphics card, and the integrated graphics chips are not particularly fast either. The graphics card or chip would be the limiting factor in how well Sims 4 would run. It's not clear whether any of these would take a GPU upgrade—that would depend on the power supply and the space inside the case, neither of which is discernible from the product pages. Even if the same model does also come with a dedicated card, it might have been equipped with or upgraded to have a better PSU, so that alone isn't sufficient information.
In terms of performance, the last one would probably do the best overall, even if that only means medium graphics settings at most. But its price is far too high for the hardware, and it sounds like 8 GB RAM and 256 GB storage won't be nearly enough for your other tasks, even if Sims 4 itself would manage. The next-best option is the third one: its iGPU is somewhat faster than the one in the first two systems.
Please don't limit yourself to options that come with two monitors, or even one. You could easily find a cheap monitor or two on Ebay or Craigslist or Facebook Marketplace, and monitors are simple to test: plug one in and play a video, and you'll know whether it's in good working order. Because higher-end monitors are a lot cheaper than they were four or five years ago, I'd expect to see a lot of people upgrading and happy to get some trivial amount for their old screens.
For the computer itself, there are lots of refurbished options from third-party sellers that have a dedicated graphics card and 32 GB RAM, too many to list even within your price range:
I can't speak to the quality of the sellers, but if you're comfortable with one of them, or with the one-year guarantee that some of them offer, it's a reasonable purchase. And like I said, you can find the monitors elsewhere, especially used. An Nvidia GTX 1050 ti, desktop edition, is fast enough for ultra settings, if not by a large margin. A 1650 is a bit faster, and anything higher than those (1060, 1660, 3050, etc.) is more than good enough, although those would drive up the price.
If you have more questions, please feel free to ask.
