Hi I am trying to upgrade my CPU on my computer. I currently have the AMD Athlon X2 4450B and I want to upgrade to the best CPU I can possible buy. I found out that the socket for the 4450B is FM2 and i hear that FM2+ CPU's will fit in FM2 mobo's, so I looked for the highest performing FM2 or FM2+ CPU. So I looked on passmark's CPU benchmark list and the highest performing one i could find was the AMD Athlon X2 240e. First off I want to know if this really is the highest performing CPU for my socket and second will I be able to upgrade to it.
