Is this good for gaming? Mostly COD, Battlefield, Etc. (Mid settings)?

I have a Lenovo G580 (Discontinued) with an Intel core i5-3219M @2.50Ghz (Overclocked with Intel Extreme Tuning Utility) [3.1Ghz?] and 6GB of RAM. I'm even using a 16GB pendrive as Readyboost and have 133GB free of 195GB. I also changed the battery settings to maximum performance and even use Razer Cortex. Will this be enough for COD? (Med settings)
