Disabling Speedstep will disable Turbo Boost, but it's a 3rd gen i7; you do not need it to Turbo Boost unless you're mocking up Pirates of The Caribbean 5 in FL or some such thing. Remember: Speedstep downthrottles the Front Side Bus when it sees fit, which will drastically decrease the performance of literally everything on the system. Speedstep is only nice to have when you're on battery, that's IT.
Also, check your overall latency of the system by downloading DPC Latency Checker here: http://www.thesycon.de/deu/latency_check.shtml
