Nvidia's product strategy is quite clear this time. It will launch two Geforce 8800GT codenamed D8P / G92 one with 256MB and one with 512MB.

Nvidia has told its partners that the 512MB version will cost between $229 and $249 at launch date while the 256MB will cost between $179 and $199.

I believe such pricing is a backup plan for Nvidia as if ATI turns up to be better with RV670 they can always adjust the prices.

NV will supply both 512MB and 256MB boards in the third week of October and it should launch it on the 29th.
