Have you watched your CPU during play with CPU-Z to ensure it isnt lowering its speed? I had a similar issue when I overclocked my 2500K. I had to disable the power saving features in the BIOS. I am sure it was just me doing something wrong, but it worked.
Also if you dont notice an improvement after overclocking, it either isnt CPU limited or your overclock is flawed. Go back to all defaults in the BIOS and just raise the multi by 5 or 6 and see if that makes an improvement.
