I did read a post in an overclocking forum where the user had a score of 1.28! Obviously due to the crashes ect one gets when 'pushing the envelope'.
Just from reading these few posts though I'm starting to get the idea that a typical user ( by that I mean someone who uses their PC frequently and to the full) will have a score of between 6 and 8. I'm hoping that with a few more users posting scores a better idea can be attained. Once we have the 'average it will interesting to see if any new updates ( SP1 ect ) will improve on this.
