Hey Asus, I have a ENGTX560 Ti DCII/2DI/1GD5 here that is starting to artifact and causing the whole PC to crash occasionally. I wanted to know if your warranty is based on the card's serial number or the original purchaser? The card was bought from Amazon in September 2012 so if it is still covered (3 years I believe), would I have to RMA it with you or Amazon? I am the card's second owner. Cheers!
