About the Card
The 8800GTS 320 MB has the same clock speeds as it's 640MB elder brother i.e. 500 MHz for the core and 1600 (800) MHz for the memory. It also has the same number of unified shaders or stream processors (96) as on the 640 MB. Basically, that translates into the same graphics core as on the 640 MB version. The only place they differ is the amount of local memory or frame buffer. Local memory would play a crucial role at higher resolutions using complex image enhancements like anti-aliasing. It would be interesting to see how the difference in performance matches to the difference in price and whether the 320MB version is a worthy alternative.
Good review but it is better to go for overclocked versions from XFX............
