So I own a GeForce GTX 1050ti and my brother a GTX 1060. How do I get the code for the bundle now? Or do you have to buy a new video card right now?
Such trivia is always only a new card. This is a buying incentive.
Of course you have to buy it. That's the purpose of advertising, that you advertise kiddies targeted to buy.
