Hi guys im building a new pc and i have to choose between the amd x4 860K the FX4300 or the i3 2100 there will be 8gigs of ram and the gpu will be ati HD 6870 or the gtx 560Ti so i will be not upgrading the pc soon so i think the i3 will be kinda bad cuz its a dual core so that leaves me with the x4 860k or the fx 4300 what u think its better?
