Has anyone had to rma a card to sapphire? If so, how good was the service? Also is there a particular email I need to use or do I just go to the sapphire US site and open a support ticket? MY x1900xt died on me yesterday out of the blue. I had my system off and went in and boot it and it would not post at all. I put the x800xl back in and it booted just fine. I tried the x1900xt in another system and it wouldn't post so I want to rma the thing. That sucks because it was an early model and it had the 1.1ns memory on it.
