@lemeul i checked online the card will cost you around 1600 including shipping, and if you still think physx is important, both ps4 and xbox one are equipped with amd chipsets, So only very few games are going to support this technology in future. And please do not think the performance for both 780 and 7970 ghz are exactly the same, Please check for reviews and benchmark's online before you make up your mind, im pretty sure you will think the same, its very close :).
