Best All-in-1 computer for Sims 4

@DenisevdWoude92  Both systems I linked can run all current Sims 4 content, plus mods, custom content, Reshade, or anything else you care to add, on ultra graphics settings.  The minimum for ultra settings with a vanilla game (no mods or cc or other added content) right now is around a desktop 1050 ti, more or less, and these GPUs are significantly faster than that.  The 1650 replaced the 1050, and the 1660 (all flavors) was the next-faster card in that same generation.  The 3050 replaced the 1650.

I do want to note that the desktop versions of graphics cards are faster than the laptop versions with the same names.  So you might see me saying a laptop 3050 is enough for ultra settings, but not by a large margin, which is true.  A desktop 3050 is over 50% faster in games than its laptop equivalent, with some variation depending on the game in question.

512 GB is more than enough for Sims 4 and your added content.  The game itself is currently around 60 GB with all packs installed.  And while I've heard of cc collections in the 300 GB range, that's extremely unusual and also slows down the game to a significant degree, so it's more for creating model sims or homes than for playing.  Still, if you decide you need more storage at some point, it's extremely simple to add another drive to a desktop—you just need to hook up two cables and initialize the drive in Windows—and quite cheap too.

For the monitor, AOC is fine in terms of manufacturer.  It makes panels for other more well-known brands (I don't remember which ones off the top of my head) and also sells a few itself, so you get a discount for the lack of name brand without sacrificing the quality of the panel.

This particular monitor is fine, but I would suggest going for an IPS monitor rather than VA, as this one is.  IPS is the category with the best colors and viewing angles, and while it's a bit more expensive than VA, it's usually worth the price to make the game look prettier.  You also don't need a 240 Hz monitor, and for Sims games at least, there's really no benefit to going above 120 or 144.  With the graphics cards in the systems I linked, you probably wouldn't get a consistent 144 fps anyway, more like in the range of 100, with occasional drops.  I would say that the upgrade to an 100+ Hz monitor is worth it: everything from gaming to using the desktop will feel smoother.

Something like one of these cheaper models would work fine:

But I think it's worth checking other sites—the selection on this one is pretty limited.  I have no idea what "iiyama" is and wouldn't trust the brand without some research, and there aren't many options outside of that.
