Best computer for all sims games

@pixidize  For a desktop, these are the specs to look for:

• Processor:  There are too many models to list, but any 8th-gen or newer Intel or 1st-gen or newer AMD Ryzen desktop processor is powerful enough to run all Sims games.  As long as you don't get an all-in-one PC, which often have laptop CPUs, you'll be fine.
• Memory:  None of the games need more than 8 GB RAM, although you might want 16 GB for multitasking purposes.
• Graphics card:  Sims 4 is the most demanding of the games you listed, and an Nvidia 1650 or AMD Radeon RX 570 will currently run it, all packs included, on ultra graphics settings.  For the purposes of futureproofing, you may want an Nvidia 1660 (regular, Super, ti, doesn't matter) or an RX 580, or the newer RX 5600 XT.
• Storage:  At least 512 GB total for your games, more if you have other storage needs.  A solid state drive is great for making Windows run faster, and Sims 3 will benefit from being installed on an SSD as well.  The other games, and whatever else you want to store (music, movies, photos, etc.) will be fine on a mechanical drive.

If you'd like help picking something out, just list your budget and country, as well as any other details that matter to you, particularly how much storage you want.  If you'd prefer to look yourself, feel free to link any options you're considering for a second opinion.
