The thing is... I am buying a 7850 GPU. Won't the i5 be an overkill? I can extend my budget a little bit and get a i5-3470 but then someone told me that CPUs should be 2/3rd the price of the GPU for a gaming rig.
That is not always the case I dont see the i5 as overkill. Also note that if you get the 3470 you 2ont be able to overclock.
