Here is the thing man, If you can afford the GTX 760 then get it. If you cannot then get the 270X. They are both decent cards and you can tweak the in-game settings for your desired performance.
If you are planning to get the 760 then save more money and get it. Either ways you can play your game on both cards, if you will ask which is better, there is ups and downs and you cannot get a concrete answer.
