The raison-d'tre of the 9800 GT is a bit of a mystery considering it is being offered in two distinct flavors of core architecture: 55nm and 65nm. With the recent deep price cuts to the 8800 GT cards, it is safe to say that the 9800 GT has come into being to try to liquidate yet more 65nm GPU cores so Nvidia can fully move their lineup to the more efficient and higher profit margin 55nm manufacturing process.
