Well what CPU do you already have?
Depending on what you have, upgrading could be a complete and utter waste of money.
Also if you just purchased that motherboard you would be better off returning it and getting an intel build. The FM2 platform is not only end of life (as in AMD has stopped making anything else for FM2), but it is a weak platform to begin with; the BEST cpu to the whole platform (the 880k) can not beat a 3 year old core i3 in performance (and mind you i3 is intel's lower end offering). A pentium g4560, b250 motherboard and 8gb ddr4 memory will run $180 and will beat the pants off of everything FM2 platform.
