I bought a GTX 1070, and it came with a code from NVIDIA for either Ghost Recon: Wildlands, or For Honor.
I haven't activated it yet, as I probably wouldn't play either of those games very often.
From what I read online, you will need a 10 series (1060/70/80/80 Ti) card in order to activate it, as it's done through NVIDIA's GeForce Experience.
If you don't, we can see if I can activate it for you, but I don't know what restrictions Steam would place on the actual game 'purchase'.
Willing to sell the code for $50 obo
