I've been reading about the comparisons between the Msi gtx 1060 vs 1070 and if you have the cash to go ahead. I'm not building (would have no idea) just comparing two desktops. Main gaming so far is only Fortnite. (May change though with decent gaming desktop) Is it really worth an extra $600?
Thanks
