Re: Is this pc good for sims with most packs and alot of mods/CC
@ClareS_Fan To run a lot of custom content, you just need the storage space for it. Memory is important too, but only up to a point—the game doesn't exactly load all the cc data into RAM, just pointers and other metadata, except for the items currently being used. (Otherwise, how would anyone with 8 or 16 GB RAM be able to play with 50+ GB of cc?)
What actually helps more is having the custom content on a solid state drive, which is one of the reasons I thought the build you linked wasn't ideal: its SSD is too small to hold Sims 4, Windows, and really any significant cc collection. A 256 GB SSD should be fine, although you'd probably need to install other games and store other data (not Sims 4-related) on the HDD. But having your cc on an HDD is certainly not fatal, it just means longer load times, relative to what you'd see if you stored the content on an SSD.
On the other hand, you could buy another SSD and install it yourself, now or later, if you wanted. It's a bit more complicated than installing RAM but still only requires connecting a couple of cables and mounting the drive in a bracket or slot that's made to accommodate it. So it's not like you're locked into this decision.
