so I know that the 770 barley beats the 7970 performance wise and uses physx witch looks amazing, but the 7970 is $50 cheaper and comes with 3 games. this is my second pc build and my first gaming build, so don't have a lot of games and the 3 games are enticing. I'm also worried about the ATI drivers support and are they are catching up to nvidia. so witch is better, 770 with better performance and physx or 7970w 3 games and extra $50.

games I want to buy for pc in future for gpu consideration
Battlefield 4
Borderlands 1 and 2
Arma 2 combined operations / day z
Arma 3
Destiny
Dirt 3
Forza 4
