Pc build for sims 4,please help!

I am a newb who hasn't purchased a pc in a decade or more and who knows nothing about available software today. I am looking to do a custom build on clx, am liking the idea of the Nvidia geforce rtx 3060 gpu, but when I put this gpu into the pc builds bottleneck calculator with anything from the Ryzen 9 series to be played on 2560x1440 resolution, it tells me I have an extreme cpu bottleneck issue and immediately reccomends threadripper 3970 or higher. What? Most sources I look at say the Ryzen 9 5950x pairs well with the rtx 3060, and I just don't feel a threadripper is necessary? I also read that many times the bottleneck calculators aren't accurate, and I do not want to pay out my nose for a cpu I don't need. Can someone please advise me on wether or not the Ryzen 9 5950x is sufficient to be paired with the Nvidia rtx 3060 to play sims 4 on 2560x1440 (QHD) resolution? And if no, Please tell me which available cpu would be better?  Please and thank you!!
