I'd like to get my first ever AMD GPU, however, I'm worried about warranty. I'd like to get one from Amazon, from a third party brand like XFX/Sapphire/Powercolor, etc., and I don't know whether I'll have international warranty, as I live in Asia and I'm unsure what to do in case I need to use warranty, as the GPU would be purchased from Amazon US/DE/UK (not sure if it matters)...
