F@H using the shaders of the GPU, so overclocking those will give you the best performance boost.
My 8800GS, which has the same 96 shaders as your 8800GTS, was scoring ~4800 PPD but the shaders were clocked at 1780. If yours are clocked at 1620, you shouldn't be too far off. My E6600 is only at 3.0GHz, so your CPU shouldn't be holding you back.
