Yes, whit radeon you get: Hitman, FarCry3, Sleeping Dgs and Medal of Honor WarFighter Limited Edition (20% off digital deluxe).
And whit the GTX, where im going to buy it, you get Botherlands 2 and Assasins creed 3 free with it.
Personaly i can find myself liking the both gtx games mutch more than the one with radeon.
but still, its about the card, not the games..
The 7970 is about 10% stronger than the 670. It also overclocks more and is more future proof. IMO it would be flat out silly to get the 670 if they are about the same price...
