Best GPU with a Athlon x4 760k

[ChrisMorris]

I was looking into the GTX 960 but I'm not completely sure. Is there any other card that could go with this better then that?

My budget is $200~

My current card is a GTX 750ti

960 is great but you don't have to spend $200 on it as I've seen them for as low as $140, save some cash.
