low fps after overclocking.

so i have a pretty old gpu a gtx 560 paried with a x4 860k... so i decided to overclock the cpu to 3.9ghz since i have a stock cpu cooler i also overclocked my gpu without moving the voltage at all i saw some big improvement while benchmarking 10+ fps boost. everything was good until i decided to run up Warface and noticed my fps was at 30 reaching down to 15 at times it used to run at 70+... i resetted my bios and afterburner settings and still nothing. my pcie version is still at x16. i'm not sure what happened and i would like some help.

Did you remove the overclock and see if things improved? If you overclocked without a voltage increase that could cause problems depending on the chipset. I would suggest removing the OC and try again. If it improves then I would say try to get a better CPU cooler before attempting an overclock.
