I was told to get a 780 ti. I found a deal on Newegg for one but I didn't purchase it before the deal ended. Now I only have enough money for a 4gb 770, 6gb R9 280x, or a R9 290x. My dilemma is whether I want to forgo Physx for a really good AMD card. I will be playing Borderlands 2, Planetside 2, Assassin's Creed 4, Skyrim, Blacklight: Retribution, and Metro Last Light.
