Really? im running planetside 2 on my old phenom2 840T, and a gt 610! on 900p low settings. Far Cry 4, I cant be sure about your specs, im running it on the g3258 and r9 280, and run it ultra averaging 45-50 fps, which is plenty for me. That game is more gpu bound, but 4 core i5 2400 should easily beat out g3258 in newer games.
That i5 should eat both those games easy, and gpu should be plenty for easy 60 FPS in both high or medium/high settings
