A few questions come to mind, maybe they've been discussed elsewhere...
Was that DDR2 demonstration done with a 128 bit bus or a 256 bit bus?
If the former, wouldn't that actually be slower than the current 9700 Pro, even with 1GHz DDR2?
How much more would a 9700 with 1GHz DDR2 on a 256 bit bus cost?
Would that much bandwidth be useful with the current speed of the R300 core, or would it be overkill?
