The first post was misleading. It seems that he has restricted budget, and when he computed, he could only go with either intel + 7850 or amd + 7870 from the send post he posted. With that, I would still go with intel + 7850. If you could cut off some budget from other parts without compromising performance then upgrade the gpu to 7870 or higher and cpu to 3570 (with k if you'll overclock) but for budget gaming, i prefer not to overclock.
