This year marks the 50th Anniversary for AMD, and it seems that Sapphire follows suit with a Radeon RX 590 Nitro+ 50th Anniversary Edition.
The details are very scarce on this one, but yeah it’s a Nitro+ and it’s shiny alright. Not that I would ever know how to make it color matching in any of my PCs, I do like the thought though. The card with its golden colored shroud has two familiar translucent fans (we assume some RGB) and shows a redesigned backplate. Other then that, your thoughts are as good as mine on this one.

AMD celebrates its 50th anniversary on May 1st so these products will likely ship soon.
