Which part is the 7.6??
Mine is only a laptop so quite happy with the figures.... only thing slowing it down seems to be the Graphics Card 
Processor
the scores break down as:
Processor,
RAM,
Desktop graphics,
Gaming graphics,
HDD
the experience score as a benchmark is definitely a waste of time as graphics, HDD and RAM can all go past 7.9 e.g. a SATA2 SDD can score 7.9 leaving no room for the faster SATA3 drives.
