Although it's not discounted, we thought it'd be worth mentioning that Mafia II launched on Tuesday and it's readily available through a number of major distribution firms. Nvidia also just wrote to us saying that any graphics card equipped with a GTX 465 GPU or higher gets a Mafia 2 digital download for free starting this week. Be sure to keep an eye out for our forthcoming performance review on the game, including extensive PhysX testing.
