Note, though that the graphic card's power is less than in my setup (HD3850 versus HD4870X2) and that he ran the entire 3DMark01.
the scaling of the entire 3d2k1 is quite different from Nature test only (=lower). Even then 3d2k1 scaled more than 06 when going from 800MHz to 1800MHz (1.1% vs 0.9%).
And yes its a different GFX card, in particular only 256MB Frame buffer (=more chance for PCIE/HT traffic during 06/Nature vs 1GB GFX card).

In general there is definitely a difference between 200MHz HT and 1000MHz HT. 200MHz is not enough while 1000MHz is enough in most cases (excluding IGP scenario). The difference between 1000MHz HT vs 2000MHz HT is much smaller (as HT above 1GHz is usually not a bottleneck).
And like I said we may not be limited to just 1.0GHz HT Link speed (just keep the HT Link multiplier at x5 and tweak the HT ref. clock).

He linked me these as well:

Pic1

pic2

I'd say the difference in GT2 is significant.
This is with Integrated GFX, right? Yes, this scenario definitely responds to HT Link bandwidth as the Video memory is behind HT Link. Would someone run 6GHz LN2 cooled CPU with IGP GFX though?
