Question

How do i find this out, thanks.

Answer 1

When they are able to perfrom specfic command requests.  

Answer 2

Open your Windows Task Manager (hold Control+Alt+Delete) or Run...taskmgr. Then, under the performance tab, you'll see each core as a seperate graph. You probably won't use the second core unless you have enough going on that you necessitate both cores. Not just idle/slight use.

Answer 3

Go to Google Gadgets  or Yahoo Widgets and find a gadget that monitors your cpu usage-type in cpu monitor in search box once you get there. These are free programs.
