Ok guys I finally got my codes and the first one worked and the second code did not, you will get a Error stating, You have already redeemed a coupon for this campaing on your GPU. Key word was GPU, here is what they did. Each Code is tied to a GPU Id number, you have to literally pull one card out that the code is tied too and boot with the other card in. I tried to redeem the code on my friends pc and it wouldn't work since its tied to the GPU. Call me crazy but this is the only way I got the second code to work. Maybe you could disable SLI and switch the primary card over to the other one, Plug in your monitor, then open Geforce Expierience. What a F@#$FEST!!! I spend $1400 and gotta jump thru hoops.
