So I have a potato pc. A gtx 1050 and an i5 650 with 4 gb of ddr3 ram. I wanted to upgrade my cpu so I got an i7 870. I successfully upgraded and when I went to play a game, I got worse fps than my i5 650. I'm not good as this stuff so I have no idea what to do. Also after upgrading to this cpu I can no longer overclock with msi afterburner. Not even the gpu.
