I have just had to RMA my Aorus Extreme 1080ti, this is my second card out of four that's faulty on arrival from gigabyte. After reading this thread I am considering asking for a refund and going with another brand.
Cheaply made piece of crap, i had the previous version the 1080 xtreme (before they renamed it to aorus for the ti) and it was pathetic. Card arrived with bent fins, a shroud that was made of paper thin metal and it wasn't even able to maintain its OC without crashing. It LOOKS a nice card but that's about it really.
The end of this vid says it all
