The very high cost of the 8800 series of nVidia's cards has been a turn off to some, and nVidia is reaching out to them. Starting sometime in February, nVidia will be releasing a 320MB model of the 8800 GTS, bringing along with it a reduced pricetag over the beefier 640MB version. On top of being a second iteration, it also has less hardware composing it, meaning it should have a good chunk taken off the price.
Aside from the reduced amount of memory, all other specs for the card are identical to the 8800 GTS. It'll be supplied as a reference, so many card makers may end up doing creative things with it. They also announced that several other iterations of the G80 are to be expected early this year.
