The Ultrabook I am using gets 4.7; but I don't play recent games on it.
Component Details Subscore Base score
Processor Intel(R) Core(TM) i5-2467M CPU @ 1.60GHz 6.3

The battery can last over 10 hours on it, and I typically get 6:30 under workload with the screen brightness set up during midday.
It totally depends what you're doing with the PC...
A base score of 5.2 can be quite respectable, or perhaps it indicates that just one or two sub-systems are holding you back.
