Some time ago, both AMD and NVIDIA began shipping some of their graphics cards, and multi-card bundles, along with free game vouchers for certain games – in this case, Ubisoft's Assassin's Creed 3.
NVIDIA initially paired Assassin's Creed III with the GeForce GTX 650 Ti graphics card, but that didn’t stop its OEMs from making deals of their own.
In this instance, ASUS is extending the offer of a free game download to buyers of its GeForce GTX 670 DirectCu II 4 GB (model: GTX670-DC2G-4GD5) and GeForce GTX 660 DirectCu II 2GB (model: GTX660-DC2TG-2GD5).
If someone doesn't like the game, they can choose a different one: I Am Alive (survival platformer/resource management), R.U.S.E (real-time strategy), Splinter Cell Conviction and Rainbow Six Vegas 2.
For those unaware, GeForce GTX 670 DirectCu II 4 GB has 915/980/6008 MHz clock speeds (GPU/boosted GPU/memory), while GTX 660 DirectCu II 2GB works at 1072/1137/6108 MHz.
