I see do you think buying the 1800X instead is worth it? or should i stick with the 1700X with this cooler?
If it were me, I'd just go with the 1700 (non-X), the stock cooler and a 3.8-3.9GHz overclock - whatever the CPU can handle at stock core voltage.
An extra 3-5% performance isn't worth $300 more. ($150 more for the CPU + $100 for adequate aftermarket cooling to stand a reasonable chance of achieving a 200MHz better OC + $50 extra for a higher-end motherboard to improve your chances of hitting the highest CPU and memory speeds possible.)
Also, depending on your luck with the silicon lottery, those 100-200MHz extra may come at a steep power cost.
