what resolution screen do you want to run the sim on?
I wouldn’t get anything below an 8gb GPU to run this sim on medium or high settings.
To be honest you will need something with more than 8gb gpu to run it in 4k can only just manage to run at 4k with mixture of low medium and high settings on oc’d Rtx 2070 and I9-9900k oc’d.
In 4k the sim will use more than 16gb ram if available and many people have found it greatly reduces stuttering. I even recently added another 32gb ram and use a ram cache which boosted my fps.
also saw a post from someone the other day who said performance improved going from 6 core to 8 core CPU.
Your gonna need a bigger SSD if you plan to install windows and the sim + add-ons and any other programs on one drive. As isn’t good to use the full capacity of the drive especially with the OS on it, when I done this my pc would come to a halt.
