you need the absolute fastest cpu clock speeds you can more than core count, i am using a ryzen 7 1800x and planet coaster uses all the cores, but as the park gets bigger, frames drop fast, you will be fine until your park gets very large. i plan on upgrading once again to the 8700k at 5ghz just so i can have a larger park, this game has amazing graphics, but it really needs to be optimized more for cores rather than clock speeds, we haven't seen over a 4.8-5.0 ghz in years, and until amd or intel can break that barrier, this game will never run well. we should already have 6 and 7 ghz cpu's. anyway in your situation i would buy the amd ryzen 5 1600 and overclock it to 4ghz if you can, with at least 16gb of system ram and a gtx 1060 or higher. i realize ram prices are sky high, but if you hold out, ram prices will drop eventually. also the new ryzen refresh chips come out in febuary and ryzen 2 comes out in june, the good news is the new ryzen chips will work in current ryzen motherboards for the next 5 years.happy holidays.
