depends which model you get. If you get the non-reference from a good brand like asus, MSI or gigabyte (there are a few others that are pretty good too) then you should have a reliable GPU with a decent warranty and decent customer service if anything does go wrong. If you get a crap brand like Sapphire (short warranty) or a reference model then you might end up with some of the problems you heard about. The non-reference cards pretty much took care of most of the issues the R9 series cards were having when they first came out.
