He seems legit. He's been on the site since 2011 ( a site used for selling used stuff, something like ebay but in my country). And it's PIB, so it has amd warranty and i can check the package when it arrives. It's just that it doesn't have a store warranty but there's another guy who sells the same but 20 euros more and you get store warranty as well, from a store called NOD. And i dont know if its worth it, if I have warranty at AMD anyway.
