Benefit of disabling duo core into single core?

[som1dies2nite]

Whats the pro & cons of disabling duo core into single core? I have a Dell D630 with a T7300 and want to know the pros & cons and how do you assign certain apps to a processor? I want to maximize the processing power I have. Thankx

There is no benefit? Maybe less power needed? Other than that you would just be crippling it.

And they are automatically assigned to different cores if the program supports threading.

Sometimes it can help some older programs work better.

Also, less power is needed

There is a windows update you can get that makes older programs compatible to the dual core.
