@AnimeNerd123 I left out the case, because a) that's a personal decision and b) it's better to let the people building the PC figure out if all your components fit. I also didn't choose a keyboard or mouse, since you might have those already. Otherwise, it's pretty much the same build as on the Cyberpower site, except with 32 GB RAM and without the free extra HDD. The total is $1,329 before taxes.

You could upgrade from an i7-10700k to an i9-10900 for an extra $70.
I don't think Cyberpower overpriced overall, in fact, just the opposite—it think its prices are great if you take advantage of the best offers and don't try to upgrade to super high-end parts. I think those high-end parts are overpriced. But like I said, you could get around that, for example by buying your own RAM kit and selling whatever Cyberpower sends you, thereby saving probably $100 overall.
The reason I didn't put a higher-end GPU in this build or the Cyberpower one is because you don't need it for your current list of games, so it would be a waste of money. Graphics cards are improving at a startling rate right now, so much so that the new $700 card from Nvidia about 10% faster than the $1,100 card released two years ago. It's a fantastic card, don't get me wrong, but someone who had $1,100 to drop on a GPU would still have been better served waiting two years to buy the newer cheaper card, that is if they didn't have a use for the $1,100 card in the interim.
You're kind of in the same place: you could spend a lot more money on a much faster card you might not need for two years, or you could wait and eventually either save money or get a much faster card than you'd be able to buy now, or both. And that doesn't even cover the newer technologies that may surface—Raytracing was only introduced two years ago, and even the fastest cards released before then don't handle it so well. The newer ones were built to do it.
This is of course your decision, and your money. But above a 1660 (regular, Super, or ti), you won't see any real performance benefit in Sims 4, or the other games you listed, unless you plan on playing at a high refresh rate or on a QHD or 4k monitor, or possibly both.
On the subject of monitors, figure out what size you want, then the resolution becomes easier to decide, and the other details can be managed from there.
