i have a suggestion although it might complicate things... i have noticed that when i run my phenom at the same clocks in xp... i get around 4400 cpu score (which would affect my total score by alot) and when i run same clocks in vista i get around 3990... but crossfirex is not compatible with xp in any way, but shouldn't these massive differences in results between different operating systems constitute them as incomparable? should we not also post what os is used and make 2 separate columns according to the os? just a suggestion
