Tom's Hardware: "The GeForce 9600 GT (G94) was the first graphics chip in Nvidia's 9-series. Although it only has 64 stream processors, it is just 20% slower than the GeForce 8800 GTS 512 and can easily compete with the older 320 and 640 MB 8800 GTS models.
It's available with a variety of different memory sizes-512 MB is standard, but almost every vendor offers models with 1 GB and even the first special models with 2 GB are already on the market. Recent tests have shown is that there is almost no difference between 512 and 1,024 MB; you can only tell when running two 3D boards in parallel using SLI at high resolutions. With current graphics drivers, the 9600 GT supports the calculations of extended physics effects in games through Nvidia's optimized PhysX technology. It can also do calculations on the GPU using Folding@Home, and with the Badaboom video encoder, it converts videos faster than a CPU."
