Your processor is 1.9 GHz CPU (up to 2.8 GHz w/ Turbo Core) according to my research. This link http://www.microcenter.com/tech_cent...ORE_Technology explains what is SUPPOSED to do. That said, it often falls short when it comes to gaming. I unfortunately can't go too in depth here, however, there is a lot of good information on the internet, and some quick googling should set you on track. If you get Turbocore squared away, there is a VERY good chance it will lead to improved and more consistent performance in ARR.
