Hey Guys, my gpu just crapped itself in my imac and I really dont want to hand my Imac over to apple for service knowing what kind of stuff they do it with it. Also I cant get past the apple logo and progress bar on start up its on a loop this is what I got in Verbose Mode ( See PIC ) Anyone knows what it could be? I would like to know what GPU out the would fit straight in without changing anything etc. AMD 6970M 2GB is what i am running now. Or do i need to buy the same GPU? Thanks in advance guys.
