Even Zotac RMA are bad. I had to wait 1.5 months to get my defected 550 ti replaced. They are dealt by aditya infotech in INDIA. Also after RMA they gave me a different 550ti edition which looked cheap but it was 550ti. They even gave me wrong driver CD. And to topup they packed everything in a second hand box of GT210. I had a spare 8400gs to survive 1.5 months but it was really very bad experience.
