The GeForce website announces a choice of Assassin's Creed Syndicate or Rainbow Six Siege is the new promotion accompanying the purchase of new GTX graphics cards. Here's word:

It’s the final few months of the year, and as always that means a rush of new triple-A games that promise to excite and delight over the Holiday season. This year, Ubisoft's Assassin’s Creed Syndicate and Tom Clancy's Rainbow Six Siege are vying for glory. And to ensure the definitive versions are found on PC we’ve teamed up with Ubisoft once again to add NVIDIA GameWorks effects to each, bringing richer, more detailed experiences to your desktop.

Enabling ultra settings and GameWorks effects at higher resolutions will require serious pixel-pushing prowess, as you can imagine, so for many an upgrade will be in order. From today, if you upgrade your system with a GeForce GTX 980 or 970, or purchase a new GeForce GTX 970M or higher notebook, you opt for bullets or blades to receive a free downloadable copy of Assassin’s Creed Syndicate, or Tom Clancy's Rainbow Six Siege.
