NVIDIA has announced a special promotion to experience Mafia II with some amazing in-your-face action. While supplies last, NVIDIA is offering a coupon code for a free redemption of 2K Games' new Mafia II game. To qualify for the free download, purchase a GeForce GPU, GTX 465 or higher (available in North America and Europe). The participating retailers are Mwave, Newegg, NCIX, and TigerDirect. Pretty good deal if you're currently considering the upgrade or getting a PC gaming setup. Mafia II was released earlier this week for the PC, PS3 and Xbox 360.
