i want to upgrade my cpu, i currently have a amd fx 4300 with an r9 270x and a biostar ta970 motherboard, do you think i should spend more buying the core i5 and a new motherboard? or stick with my actual board and buy the fx 8350? will i see an fps difference? i play most of the time battlefield 4 and my fps are kind of decent 45-65 on high with mantle 40-55 on d3d i think
