Well, GDDR5 can use different trace lengths to memory chips, which I'm sure you know. If the shared frame buffer rumor is true I'm guessing that the trace lengths between a memory chip and the two RV770s will need to be equal, but even then board design should probably be less complex and have less layers if the memory placement is good.
