hi i currently have a a gigabyte 78lmt usb3.0 in black, gigabyte r9 270x windforce, and a fx6350 cpu in my mind my weakest link is the motherboard but i know it can still go with a r9 290x and a fx8350 so should i upgrade my gpu or cpu next? im so unsure on the 3 components what to upgrade any ideas would be great guys ty
