Gigabyte (1366 and 1156) boards generally allow easy access to the 1st extra turbo multiplier, and do not TDP throttle, so using it is just like having an extra non-turbo multiplier.
For the higher single or dual core turbo states to function, the various C# states and EIST usually have to be enabled, because Turbo Boost won't utilize multipliers over +1x unless it can put other cores in a low power state.
...rightful liberty is unobstructed action according to our will within limits drawn around us by the equal rights of others. I do not add 'within the limits of the law,' because law is often but the tyrant's will, and always so when it violates the right of an individual. -- Thomas Jefferson
