If you can get a FX8320 for allmost the same price as the FX6350.
Gigabyte GA-970A-Ud3p is capable to handle FX83xx cpu´s. But im personaly not realy a big fan of Gigabyte am3+ boards, but thats personal.
Also the 270X 4GB isn´t worth it either over a 2GB version, the 270x isnt powerfull enough to utilize that amount of vram. If you come into graphical situations that you need 3GB+ vram, then the gpu it self will become a limited factor anyways. 3/4GB vram is only a thing for highend gpu´s. like 780 / 780Ti 290 / 290x / 970 / 980 and such.
+1 to everything here. I too don't like Gigabyte but thats just me.
Also look into the 270 it is just a lower clocked 270X. You can usually OC them to the same speeds or higher. Much cheaper too.
I'm not sure about in Europe, but I know in the States that the prices on the AMD cards are tumbling. You may even be able to get an R9 280 or 285 for the same price or a little more.
