Is the best today. You might eek out UHD 4K on The SIMS too.

In the more modest price range The Sims 4 should be fine on say the 1080p monitor (monitor matters on this question) on the 1050 Ti (do not get any less!)

But for other games I'd like to see the 1060, 2060 or 1070. What you get may be set by your budget.

On the RTX 2080 and 1070, be sure to check if your PSU is up to the task. You want a SINGLE RAIL PSU of the prescribed wattage.
