Some are lucky to get good service while others get the shaft.
My friend was the one to get the shaft as it was his 2900 XT, he didnt want to deal with the RMA gave it to me tried to see if I could get it to work which I couldn't. I submitted the RMA and paid for the shipping and out came a 4870. He learned from that.
Either way I would go for Asus or MSI. I prefer the Asus design but it might not be pratical in some cases.
