gamercora22 Strange, the Nitro I linked listed 16 GB RAM on the search page but only says 8 GB on the product page. Sorry about that. The info about upgrading applies equally to this laptop too though, in fact the Nitro model is one of the easiest to upgrade.
An RTX 4060 is absolutely not necessary for Sims 4. It's nice to have if you're going to pile on the high poly custom content and Reshade filters, or record your play, but the 4050 can handle everything the game throws at it without trouble. So whether it's worth the money to upgrade depends on your plans for the laptop, and whether you might play other games that are more demanding, and of course what that money means to you.
If you do want to upgrade, you could do better on the price though:

Note that the Acers are only on sale for a couple more hours. But there are plenty of options for around $1,000, so there's no need to rush the decision.
If you really do want to save the money, I found this one that comes with a rebate:

This model tends to run hot and noisy, but it's not a problem if you play with the laptop on a desk and with headphones on. I wouldn't recommend it if you like to use speakers though. My brother has a similar one, and when we're both at our parents' house and he's playing almost anything, I can hear the fans from three rooms away. I'm not kidding.
