@AccurateDino That is going to be a great system, and as igazor said, over the top for Sims 3, not that it's a bad thing. If you want a second opinion though, I have a few thoughts:
- Spend the extra $10 or whatever and get 3200 MHz RAM. Ryzen processors love fast memory.
- While the SSD is more than fast enough for Sims 3, Windows and possibly other apps you might want to run will be faster on an NVMe SSD. Of course, they're more expensive. You could also install one at some later point if you decide you want one; it's quite simple, easier even than installing a SATA SSD, since there are no cables involved.
- No idea what more intensive gaming you're doing, but a 2070 Super will run most games* out there at well above 60 Hz in FHD (1920x1080), and often even in QHD. Whether having such a fast GPU is beneficial or massive overkill depends not only on what games you plan to play, but also on the resolution and refresh rate of your monitor: playing on a 60 Hz FHD monitor, your computer wouldn't be able to use all that extra speed in almost any current game. Besides, a card that nice deserves a monitor that can display its full capabilities.
- If you're thinking of futureproofing for games that haven't been released, it's probably better to get a merely very good card now and plan on upgrading it in three years or so. At the rate GPUs are improving, the 2070S will likely be bypassed by somewhat cheaper cards in a few years, plus there will probably be some new very cool technology that current cards don't even support but which new ones run easily.**
Still, this system, with or without any tweaks, should run Sims 3 as well as it's possible to run the game.

** A good current example would be Raytracing, which works (barely) on some 10-series cards, to a limited extent on the 1660 ti, and very well on 20-series GPUs, which were built for it. There aren't currently that many games that employ Raytracing at all, and fewer that take full advantage, but more are coming, and it will probably be a standard feature of high-end games before long.
