Just wanted to share my experience.. I have RMAed 3 times for my sapphire r9 290 reference.. the 1st and 2nd time the card gave artifact after few months of usage.. until they finally replace it with brand new tri-x. Even though it took me 3 times to solve my problem, im still satisfied because the RMA process only took 1months++ as they promised. And also customer service was great! Thanks to hikari
