new pc for Premiere... is the correct choice?

i need to change my pc...now i think a:

i9 xxxxx ssd gtx1080, 3 ssd (how is reeccomended in premiere..) 32 gb ram ..... total 2000 and more dollars for what?

when i try to work on a dji mavic file or go pro file or 4k file, is not possibile (jerky playback , not smooth..and if you apply a colour is worst) and i need to convert all in pro res?

they are serious?

i read a lot of people that spent a lot of money with new MONSTER PC and have the same issue (jerky playback etc)
