Nvidia announced today that you can get a free copy of Ubisoft's much-anticipated open-world game Watch Dogs for PC with the purchase of a qualifying GeForce GTX graphics card.

The offer is available for GeForce GTX 660, 660 Ti, 670, 680, 690, 760, 770, 780, 780 Ti, or Titan Black graphics cards only. The promotion began today and will be available "for a limited time" through retailers like Amazon and NewEgg, among others. Full details about the Watch Dogs Nvidia promotion, including a list of all qualifying GeForce GTX graphics cards, are available at Nvidia's website.

The free Watch Dogs codes are redeemable through Ubisoft's own Uplay digital store. If you have a code, you can redeem it now, but of course you can't start playing until May 27.
