The 7870 is actually a sizable performance jump from the 7850. I love mine, I actually sold my two 6950s and got a 7870 and a 7770 for my kids computer. Its very quiet and plays all my games at 60FPS or better at 1080p. Like said previously by 'drums101', only go for the free games if it is something you would actually want to play that would factor your purchase. Otherwise go for the better performing card. ASUS makes some really solid cards too. And so does XFX. It really comes down to if you want those games and what settings you plan on playing at.
