pc advice appreciated

lannahhowe  This system is overkill for Sims 4, not that that's a bad thing.  If you wanted to save some money and weren't going to need the extra power for anything else, you could drop all the way down to a desktop RTX 3050 for the graphics card.

The 3050 is still capable of running the game on ultra graphics settings, with plenty of room to spare.  If you piled on the high poly custom content and added ReShade or similar, you might start to notice some slowdowns, but you might not, depending on what content you were using.

The desktop RTX 4060 is a lot faster than the 3050, so much so that Sims 4 can't use all its power, even with lots of third-party content.  So it's a good compromise if you want to save some money but would like some extra power to play with.

As for specific suggestions, I can have a look around.  Please list your budget in that case.

I did find this system with an RTX 4060 for someone recently, in case you'd like to compare:

The processor is a bit slower but still more than sufficient, and it only has 500 GB storage instead of a full terabyte.  But that's still more than enough for Sims 4 and a giant pile of custom content.
