GeForce 9800 GX2

This new GPU replaces the GeForce 8800 Ultra as their most powerful Graphics Processing Unit. Last generations GeForce 8 Series has been NVIDIA's most successful GPU to date as gamers who invested in the high-end 8800 GTS and GTX graphics card have enjoyed well over a year of top-notch 3D performance and image quality to match.What makes the GeForce 9800 GX2 unique is that it features two GPUs working in tandem on a single graphics card. However, unlike the architecture of a dual-core processor, where one of the cores may be idle, the GPUs on the GeForce 9800 GX2 are fully utilized when they operate in SLI (Scalable Link Interface) or Multi-GPU mode. At the price of about 550USD and a memory amount of 1024MB it's quite the beast among graphic cards.
