I agree with you sensesfail in the sense that is does seem a little low. Have you tried ending some menial processes for the task manager in Windows? That helps the CPU out a bit.
Maybe if you tried overclocking, you can push that score up. But don't try it if:
1. You don't know how to (obviously)
2. You don't have the money to buy a replacement if you acidentally go too high and burn out something
But just try the usual stuff (like disk defragmenter and disk cleanup), as they might help for an axtra few points
