Lets go back a yr, 780i HT link between NB and SB, running 2600 or 2800HT along with PCIE at 141 with dual cards made a massive gain...BUT things were different.
1 the NB supplied 16X and the SB supplied 16x PCIE so an overclock to the PCIE bus would yield gains if the bus connecting the domains had a frequency increase.
2 790FX supplies both 16X slots, so the ONLY gain we should see with the video cards would be PCIE clocking until the transfer of data from PCIE to HT was the bottleneck then an increace in HT will be needed from the NB to the CPU.
So...why does increasing HT lower 3D performance...if anything an increase in HT bus should do nothing if the bus is already not the bottleneck?
Something is not right here
