as in it will have no affect while folding is off.
Folding both will certainly increase productivity, but the CPU won't be nearly as productive as the GPU. The post below is also a very good point that I had not mentioned: You will have to intentionally cripple your CPU in order to keep your GPU effective.
By devoted to folding, I mean this: When F@H is running on both your CPU and GPU, the PC can't be used for any other task. Not to browse the web, not to check e-mail, nothing. It will use up all of your system's resources. Consequently, every time you or another user wants to use the PC for anything that is not folding, then F@H will have to be paused on the CPU, the GPU, or both. And since both CPU and GPU work units are time-sensitive, pausing has the immediate impact of lower points for you and less work done for the project. So yes, you can pause or even stop F@H from using your system, but not without cost, and not without inconvenience to you and other users. As someone who tried folding on his mom's PC in the past, I can tell you that you should prepare to overcome a large learning curve there.
