Hi, I somehow end up with 2 of same GPU lying around which is RX580 Sapphire 8GB. one of them is limited blue one and another is normal one.

please note that both GPU are in the heavily used condition though, one of them have some rust on the port and another are in similar condition. both of them perform fine.

I got them for like $75 a piece so it okay

what should I do?

Current Spec:

CPU: Ryzen 1700x
Cooling: Noctua U12S
MB: Asrock 470x Master
RAM: Corsair 16GB 3000Mh (CAS16)
PSU: Corsair HX850i
