Hi, I'm trying to build a PC rig and I have yet to decide on a CPU. I want to try and get a CPU that can run games such as Battlefield 3 at an average speed. I am planning on getting the AMD Phenom II X4 965 Black Edition (http://www.newegg.com/Product/Product.aspx?Item=N82E168...) with a XFX HD 6870. However I don't know if I should step up my CPU and get maybe an AMD FX-6300 six-core processor (http://www.newegg.com/Product/Product.aspx?Item=N82E168...). Could someone please tell me whether the Phenom would be fine for a game such as Battlefield 3 or should I step up the CPU to FX??
