With everything i have on mine its coming up 720 max usage so i dont really wanna go 750 as i heard the 3080 spikes sometimes so i went for the 1000kw. Wasn't much extra considering what i already paid.
Hoping mine arrives before Christmas as i really don't wanna go back to console. Even had a better experience using Geforce Now to play other than using my console. Ordered bit late on release day though so ill be waaaay back, 4pm.
