No 8300GS
However, you can find the 8300GS if you do a web search. It has Turbocache, meaning it eats up part of your system memory for graphics, something better avoided.
I would tend to choose the 1300XT if you can confirm it doesn't have Hypermemory, the ATI equivalent of Turbocache. Most of the 1300XT's don't.
If both alternatives have Turbocache/Hypermemory, then I would tend to go with the NVIdia 8300GS because it has a more recent archtecture and NVidia drivers are more versatile regarding scaling at lower resolutions or scaling while maintaining correct aspect ratio. This is more important if you have a widescreen monitor.
