GeForce 9600GT board diagram pictured
We've gotten our hands on a board diagram of the 9600GT and it looks as if these cards will be available with a wide range of memory options from the word go. The diagram below lists 256, 512MB and 1GB as possible memory configurations and it also suggests that we'll see DDR2 and GDDR3 based cards.

It also looks like some 9600GT's will get dual slot cooling judging by the rear bracket configurations shown here.
