Hello, I have been looking to purchase a new Ryzen 9 3900x from a authorized retailer. The only issue is everyone is sold out!!! I have now turned to searching on Ebay and see them marked up to $600+. I wanted to know if I do purchase one from Ebay will I still get my 3 year manufacture warranty? I have been patiently waiting for weeks!! I am trying to make my decision this this week on AMD or Intel Core-I9.
