I wonder how long the cards last with that twist with the heat and th3e twist would imagine that some things would start to pull out. I had a mother board do this I forgot to use some of the screws and was folding years ago using the cpu and after a while weird things started to happen I pulled the board and it was warped which seemed to fix itself when I used "All" the mounting screws I would imagine since vid card can run very hot it would happen more often.
