Apparently 06 is quite sensitive for HT Link frequency as well. Check the graph Tye sent me a few hours ago:


(All credits go to KTE)

Note, though that the graphic card's power is less than in my setup (HD3850 versus HD4870X2) and that he ran the entire 3DMark01.

He linked me these as well:





I'd say the difference in GT2 is significant.
