video cards

i've got a 1060 in here and it gets the job done, but previewing (in vegas) gets pretty jolty and almost undoable when fx are loaded

is a 1080 what i want? will that do the trick?
i7-6700K, 16gb ram. basically a 2017 model i did for moderate gaming. think i'm gonna buy a 1080 but i don't know yet.

the settings had to be changed because my 1060 was causing it to crash, so it's on default now. slow rendering, shitty previews. it's only version 13, i should probably upgrade that first eh.
