I can lock my CPU using Throttlestop from Techpowerup, http://www.techpowerup.com/downloads/Utilities/ThrottleStop/ and that helps my FPS by a good 5-10fps.
I've got a 420m overclocked to a 555m clock speed and it doesn't do much. I think another huge bottleneck that is just physically limiting the system is bus speed, the 128bit bus with DDR3 GPU memory is a big killer. GDDR5 with a high bus width should help allow the GPU to be fully utilized. But it also seems like new GPU's take forever to hit the market. Guess its just a thing with new tech to reach the mobile industry.
