it all depends on the gpu! 700= transistors is alot of space and nvidia could have something up their sleve. and if the r600 has 64 shaders and the nvidia has 128 then i think it is an even match or mabye even in nvidias favor because 128 shaders is a lot of power!!!!!!!!! and there is no point to having so much unused bandwith. so only time will tell if all this bandwith is a waste. looks to be a beast tho
