Hello, when i go into task manager under the "performance" tag my CPU has two graphs like a dual core, they also show different readings. Is this normal? In the "View" menu in "CPU History" the "One graph per CPU" option is selected. My CPU is a Pentium 4 2.8Ghz. I was wondering if its not normal does it affect my computers performance in anyway? Thanks, Nick
