@soogyus Both of the computers you listed are overkill for Sims 4, even with custom content and Reshade, not that that's a bad thing. But you can do better for your money. This one has the same hardware as the Best Buy option you listed except that its processor is a year older, but that won't make any measurable difference to Sims 4. Skytech's build quality is better than Cyberpower's these days as well, although Cyberpower is still fine in most cases. It's also $200 cheaper:

I wouldn't get the Amazon option you listed, to be honest. Although the processor should be more than fine for Sims 4, I've seen a few examples of the game running slowly for no apparent reason on this particular generation of AMD CPUs, and I was never able to figure out the cause, much less fix it.
You can save more money if you want though. These two are also overkill for Sims 4, even if their hardware is not quite as powerful, and should be able to handle your cc and Reshade settings just fine as long as you're not playing on a 4k monitor:

The first one has a faster graphics card and the second one a faster processor. If you're more worried about graphics rendering, for example if you want to use very demanding Reshade settings, the first is the better option. If you're more concerned about game engine issues like simulation lag, the second one is better. They're both more than good enough though; I'm not sure you'd notice any difference between the two while playing.
If you're willing to shop elsewhere, this one is essentially the same as the second Best Buy link (faster GPU) except that its processor is a generation newer. It's cheaper too:

And these two have a 3060 and a 3060 ti, like the Amazon and Best Buy options you posted, respectively. The first one's processor is significantly better than the Amazon option; the second is equally good for gaming as the Best Buy option. And they're cheaper. The only downside is that the first one doesn't have as much storage, but 500 GB is still plenty, and it's actually quite easy and reasonably to add another SSD later if you want. Plus, like I said, Skytech generally has very good build quality for this price range.

If you'd prefer to stick with Amazon or Best Buy and want to keep the price down, this one is almost the same as the Amazon option you linked except for its newer and better processor, and the fact that it only has half the storage:

I know this is a lot of options, but it becomes simpler once you decide whether you really want the extra power of a 3060 (regular or ti) or not. Then you can cross off half the options and go from there. As I said, a 1660 ti or 2060 is still going to do what you ask of it, but maybe you want the faster card for other reasons. The one thing I do know is you definitely don't need to spend $1,400 on this computer.
If you'd like help picking out a monitor, or you want me to look at the option(s) you're already considering, just ask.
