NVIDIA is going to launch yet another game bundle for customers buying a GeForce GTX 1080 or GTX 1070 graphics card including For Honor and Tom Clancy’s Ghost Recon Wildlands.
To redeem or activate the free games you have to install GeForce Experience and register. The two games aren't available until February 14 and March 7 respectively, in other words if you buy a GTX 1080 or GTX 1070 before the launch you will get a preorder code.
