Anyway, the bandwidth might be enough for 5850, due to the crippled Cypress, but it is not enough for 2 "full-option" Cypress like HD 5970 has. What is changed from HD5870? The bus is the same, the number of shader procesors is the same, the only different things are the clocks. Which give less bandwidth/ GPU compared to HD 5870.
Yeah, Warhead either I guess.

DX10 is another matter altogether.

The performance issues could be due to loosened timings on the memory. Has anyone been able to read the voltage used for the GDDR5. I haven't got there in my testing but it is possible that ATI lowered the GDDR5 voltage in order to keep power consumption under 300W. Therefore, they also needed to loosen timings in order to stay at the desired speed.

Man, I'm grasping for straws here...
