Why not pop them a FREE email and ask them for yourself? They have been fine for me the couple times in the past 6 years when I had a question or needed to RMA a card. And I have used dozens of their cards. But most issues can be solved by yourself. What is the issue as maybe it isn't really a driver or ATI issue? Maybe someone here can help.
