I reckon that your WEI scores (for what they are worth) are pretty good. Your SSD index is not bad really for a SATA2 drive. I have seen worse scores with some SATA3 drives. I think my processor score is the same as yours and as a matter of interest it didn't move much, about 1 or maybe 2, when I overclocked it from 3.3 to 4.3Ghz. Just goes to prove once again how flaky the WEI is.
I will be interested in how you get on with the RAMdrive.
