if you arnt getting lower FPS, you should not be worried, your drivers probably got updated and now the boost function is showing the clock rates correctly.

that is normal. 6xx NVidia gpus from 650ti boost and above have a "boost"clock. which increases the clock speed on demand, and will throttle back depending on temperature, power etc. You can keep the boost clock higher by keeping temps below 70c and increasing the power limit with msi afterburner.
