No it is not possible because the x2 is a am3 processor and the x4 is a fm2+ socket processor. You would have to change the motherboard to a compatible fm2+. While that is an option, you can also get a fx series processor with a TDP of 95w or less because it's all tat board supports. You will not be able to overclock though. And what is your GPU? A low end GPU will bottleneck your system.
