Hexus reports NVIDIA may have another rebranded GPU up its sleeves; the GeForce GTS 240. This one seems to be an overclocked GeForce 9800 GT with passive cooling and 1GB of GDDR3 memory.
The card in question will be passively-cooled and feature up to 1GB of GDDR3 memory. Conjecturing somewhat, we'd presume the card to be an overclocked GeForce 9800 GT. It'll slot in just below the imminent GeForce GTX 250 and feature the same HDMI, VGA, and DVI connectivity.
