Bought a graphics card from OcUK 18 months ago for around £320. The card developed a defect a week ago. I phone OcUK for technical support and RMA but it turns out the card had only one year warranty. Is this acceptable? should I take it further because I'm frankly pissed off that the card develops a defect only 18 months after purchase, which is only 6 months after the warranty expires. What should I do?
