So as our video cards got enormous and heavy in the past few years, there's very little supporting all that weight. I'm concerned more for the PCI-E slot itself than the card. Aesthetically, it also looks unsightly to have your card clearly sagging down in an otherwise, nice, taut build. I'm currently using a couple black zip ties from the top of my case (Corsair 760T) down to the heat pipe on the corner of my 970. You can barely see it but I may use some fishing line instead (to be even less noticeable). What other methods do you use to support your card(s)?
