Hello, I currently have a AMD Phenom II X2 565 in a Gigabyte GA-770-USB3 MOBO. It is the AM3 set. What would be the best processor to put in for gaming? Would it be the AMD Phenom II X4 965 Black Edition Deneb 3.4GHz Socket AM3 125W Quad-Core Processor? I also have an EVGA GTX 750 Ti 2gb. Thanks in advance!
