That is a fine processor. What kind of PSU do you have? The answer to your initial question will depend on your answer to that question.
Oh sorry. Seasonic G 550w 80+Gold
Good quality PSU. If you have the budget, your CPU will easily accept a 970 and that card will improve your performance by a significant margin. The 660sc is a decent card still though.
