The GeForce 9800 GX2 have been dismantled a long time ago, but NVIDIA still holds the card’s detailed specifications tight. But finally we now know their little secret and decide to post it here.
The core clock is similar to 8800GT’s, but as you can see, memory clock raised up to 1000MHz. Also, source mantioned the card supports OpenGL 2.1.(8800GT only supports OpenGL 2.0).
