In the About This Mac tab, my Core i7 860 is showing up as a 2Ghz core i5. However when I run geekbench it shows up as a core i7 860. I used the new iBoot supported installer, and the latest Multibeast, gigabeast installer for my P55-UD4P mobo. Also, my geekbench score was an abysmal 5872, far off the 8900 i ran in a previous install. How can I fix these issues?
