I want to know if it is worth it to upgrade from an AMD Phenom II X4 910 to AMD Phenom II X4 965 Black Edition. Will it increase my gaming performance (Battlefield 3)? Or is it better to upgrade my graphic card from a GTX 550ti to a GTX 560ti?
You would see a CPU improvement especially if you then overclocked the 965BE. You would see a gaming improvement if you did the 560ti as well though. As far as visual improvement goes I think the 560ti would give you more straight away (in FPS you won't suddenly be running at ultra)
