The first GeForce 8800 GTS cards had 96 stream processors and 320MB or 640MB of memory depending on the card. The new G92 based GTS cards all have 512MB of memory and all have 128 stream processors, 32 more than the previous GTS cards. Other benefits include PCI-Express 2.0 support, PureVideo HD engine support. The reference clock speed is 650MHz for the core and 1.94GHz for the memory. This should also prove to be a significant step up from the GeForce 8800 GT. 400W power supply is what Nvidia lists as a minimum to use the card but this will vary depending on the quality of your power supply. A single six pin PCI-Express power connector is used for power.
