For my next pc I want an itx budget build that's got support for all the AMD's latest like mantle.....
Anyways I want an apu like the 7850k. Later I will upgrade to a physical gpu and run them in xfire. Are there any restrictions as to which gpu i can use? Can I run a 270x because that's the gpu I want?
