ok so here is the list. please note i do NOT believe in over clocking.

CPU: AMD ryzen 9 3900X
MB: MSI MPG X570 gaming pro carbon
CPU Cooler: cooler master ML360R ARGB
RAM: G.SKILL trident RGB series 32GB DDR4 3200
SSD: WD Blue 3D NAND 1TB SATA III 6Gb/s M.2 2280
PSU: Corsair RMx white series RM850X

i plan on gaming with this build. no video editing.
i ALREADY own an MSI RTX2080 GPU

EDIT: i am questioning the compatibility of the MB and PSU. MB says CPU power requires an 8+4 connection. and the PSU dosent specify it has that connection. is the EPS/ATX12v 8-pin for the CPU? and the peripheral 4-pin compatible on it ? so i would use both these?

it is all compatible,

I'd consider stepping up to 3600 CAS 16 or 3733 CAS 17 RAM instead of 3200. a decent speed increase for not too much more money.

the PSU will work, but 850W is overkill fora 3900 and 2080. You can get by with 550-650W just fine.

looking at the specs of the ryzen 9 3900x. it says memory type is DDR4 3200. i thought that ment 3200 was the max the CPU would do. and thanks about the info on PSU. i want some Over kill so i will look at 750

the 'sweet spot' for Ryzen 3xxx series chipsin terms of memory responsiveness is 2 ram sticks at 3733 CAS 17, with 3600 CAS 16 and 3200 CAS 14 just a step or two behind. stepping up to 3800 is actually slower than any of those 3.

3733/17 responds in 15 clock cycles.
3600/16 responds in 17 clock cycles
3200/14 responds in 17.5 clock cycles
3800/18 responds in 20 clock cycles

almost all of the 3733 ram im looking at says intel chip set. does this means its not compatible with my AMD CPU?
