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).
I see what you mean. To be honest, I failed to add a very important sidenote, which is: "Yes, 3D performance decreases when lowering the HT Link frequency, however, the performance gain you obtain because the lack of a coldbug, which makes it possible to clock your CPU frequency much higher, definitly outweights that loss."

I ran some performance scaling tests on the CPU frequency as well and you can see Nature scale quite impressively .

People run laptops under LN2, so why not . That's not your point, though.
