You are completely right...however I have been watching GDDR5 since quimonda first released specs(in such a way that I know that up pic there is from a quimonda document)...I fully understand it's possible(I was saying yes months ago, I had a big part in the shared framebuffer rumour, when ATI guys were saying no), but I question only whether the pcb design will affect overall cost as much as it should...given the intended prices for such cards. I see the same cost as making 512-bit membus pcb...which gives me a $575 retail price for 4870x2's...I am hoping for less cost..$499...

Again, I'm the ATI fanboi, but i like to keep it real. If they have pulled it off as I hinted like months ago, they've got nVidia under thier boot. If they don't have shared framebuffer, i'll still buy if i get more than 512mb of framebuffer for each gpu.
