When I switch back to my XFX GTX 260 Black Edition when I rma'd my 480, I noticed a lot screen flickering and artifacts. When I got my 480 back I just forgot about it. Then I let my friend borrow it when he rma'd his card and he was experiencing the same issue I was having.
Now I'm thinking of sending the card to XFX. I'm pretty sure xfx doesn't have any 260 black edition.
What do you guys think if they replace the card they will give me back?
