You could over clock the cpu a little and make sure the ram is running the same frequency as cpu, i got my score from processor being 3.0 to 3.3 and ram being 4.1 to 4.3.
Then if you could improve the hdd your score would be slightly better
My overclock was quite small, from 1913mhz to about 2039mhz, the cpu being sync with ram makes most of the difference i think..
Maybe this will not apply to you my machine is old, but thats how i improved my score/performance.
See here what i mean about frequency: http://valid.canardpc.com/show_oc.php?id=516502
