These GPUs belong to the junkyard, but isn't this a part of a new trend?.

nVidia has always been re-branding by just re-naming and re-boxing the same junk, almost untouched. But I have seen a few special re-branding lately. They are refreshing and re-branding at the same time, by mixing several of the same (or different) junkyard-worthy GPU on a fresh PCB design.
