I had my old 460 gtx die on me. I contacted Gigabyte about the warranty. I purchased the card new in 2011. Gigabyte's claim is that the warranty is from the date of manufacture not purchase. They claim the card was manufactured in 2010. That means when I received the card it was already one year into the warranty. Effectively I one get a 2 year warranty instead of 3. This is the first product I have tried to RMA and never run into this before. Is this normal?
