As far as these being just a G92 refresh, how do you explain the 512 and 448-bit buses? Would there really be that much of an improvement simply through a core refresh that Nvidia needs to increase the bus size?
An assumption/misunderstanding of the rumors.
9900GTX/GTS should be the G92b.
This whole thing got out of hand when one person thought the July launch meant GT200.
