NarbiusTheGreat :
It will perform very well with the r9 270x. What types of games do you plan on playing? GTA V will be able to run at medium-high settings as long as you change around the settings. BF 4 can run on that setup (Not on max settings). In other words most games can run on that build very well.
I like to play a lot of H1z1, cs:go, Batman Arkham city, Skyrim, Gta 4, and someday I'll buy GTA 5.
