I was browsing Newegg and noticed this sweet offer, a free copy of Mafia II attached to the Nvidia Geforce GTX 465 card and above.
Buyers of the card will get a code to download a full copy of the game through Steam. The deal is available on these models:
MSI GeForce GTX 465
PNY XLR8 GeForce GTX 480
ASUS GeForce GTX 465
and here’s a general search for other cards with the offer.
