You should see an increase automatically due to more registers being available (assuming the compiler makes good use of them). Other than that, I suspect the only increase you will see is in parts that use "long long" or __int64.
Also keep in mind, compilers are very new to 64bit compiling - it will take a while for them to optimize to the full potential.
