Hello, I purchased an AMD Radeon Sapphire 270x graphics card in April/May time of 2014. I was assured it was reliable and would last me for at least a couple of years. However regardless to massive problems I had with it at the start it completely stopped working altogether last month in October. The only graphics card I could replace it that was available was the AMD Radeon Sapphire r9 390x which has insanely set me back money wise. The shop I purchased the 270x from last year told me its over the 12 month warranty and they can not do anything about it, but told me to message AMD about it. Is there any options I have with returning this card to you? and how do i know that my 390x wont do the same?
