@SophieBxnks When I talk about an upgrade, I mean adding or replacing any physical component(s). But in practice, the point of this build is to make sure that most upgrades are unnecessary. The exception is the graphics card, because cards are improving so much so quickly these days. Even a really good card will be somewhat outdated in four or five years; it can’t be helped.
On the subject of Sims 5, it’s in all likelihood several years away. The developers have said that Sims 4 has at least a couple more years to go, with new packs coming out at the current pace. And then there will probably be a yearlong gap before the next version is released. (That is, if it ever comes out at all.)
We can’t know what that game will look like, but I would expect that even at its most ambitious, the base game will run beautifully on a 2060. After all, EA knows that much of its audience is comprised of casual players who can’t or don’t want to spend a fortune on a proper gaming PC. If it runs okay on a basic laptop, it should run on ultra settings on a 2060. And by the time the more demanding expansions start rolling out, your son would be ready for a new graphics card anyway. Again, this time frame would probably be around four years, give or take, unless he decided he wanted to play some demanding game in the interim and needed a new card. That’s why I’m saying there’s no point in getting a better card than a 2060—you can’t possibly know what he’d need in a few years, and the cards available then will be a lot faster than anything you’d want to buy now.
I don’t know what connection your 55” TV has (probably HDMI), but the 2060 has DisplayPort, HDMI, and DVI connectors. These are standard with any modern graphics card. If necessary, you could get an adaptor, but you’re probably already covered.
A solid state drive is much faster than a traditional mechanical drive. SSDs come in a few different flavors, from reasonably fast to faster than you’d ever need for gaming or other normal use. The default configuration, which I picked initially, is usually a smaller SSD and a larger HDD for storage, but with this build, you can choose whatever you want. I could replace the HDD with a second SSD for storage, although it wouldn’t matter all that much. As long as Windows and applications are on an SSD, they’ll load extremely quickly. Stored files like music, movies, and photos will play back the same on a mechanical drive as they would on an SSD, which is why people usually go for the much cheaper HDDs for storage. But, like I said, at this price point, you can get whatever you want, including a well-respected (and more expensive) brand for each drive.
So let me know anything else you want me to take into consideration, and I’ll put together another build. The one thing I can’t pick for you is the case—style is highly personal. (Besides, I’m not a fan of flashiness in general.) If your son knows this computer is coming, you could ask him to pick one from the available options. Otherwise, maybe you can guess from what you already know about his preferred style. And don’t worry about compatibility; if you happen to pick a case that doesn’t fit the existing parts, the site will give you a warning and ask you to pick something else instead.
