This is exactly what the rv770 needs to take advantage of its large ammount of memory bandwidth. I kinda knew this would happen weirdly enough when I thought about how much the 2000 and 3000 series OC'd, was just a hunch mind.

Will probably be my next card. So excited!

The reason the HD2000 and HD3000 cards are bottlenecked by the core is because the shader clock is permanently set at a 1:1 ratio to the core speed, where as nvidia cards have unhooked shader clocks, and they are significantly faster than the core speed.

With the HD4000, the shader speed is also unhooked from the core speed, and the core will be close to or exceed 1GHz. Not to mention GDDR5 memory, with the (slight) possibility of a 512-bit memory bus and double the TMUs (which has remained the same since the X800 series).

The HD4000 cards are going to own quite hard indeed.
