Caporegime
Well unless they've somehow managed to make it lighter than the last g1 980 ti its a certainty to sag. This is taking up close to three slots from word doing the rounds so id be amazed if it has no sag.
If the weight is more to the center of the slot (it doesnt look much longer than the board its connected to) then twisting/torque on the slot will be less?
And I think I know which board thats plugged into and its 23.1CM wide (a tiny bit under normal ATX width) .
