There are three important factors that make GeForce 8800 GT a better run for the money. First and foremost, the GPU is manufactured using 65 nm process, thus making it a smaller and cooler chip. The second change involves the way G92 communicates with the rest of the components; PCI Express 2.0 which in my opinion is more of an evolution than revolution (sort of like AGPx4 -> AGPx8). The last thing that has been overlooked when looking at enthusiast SKUs is VP2 or Visual Processor which takes care of HD video decoding.
