According to the Inquirer, NVIDIA is preparing a new entry-level graphics card to replace the 7300 based on the G80 architecture. 

This is set to replace Geforce 7300 from the market. Nvidia is really having problems making a real impact on the entry-level market but maybe will have better luck with this introduction.

The chip is a cut down version of the G80 and will probably come up with some odd memory controller number. It will support Shader Model 4.0, the unified way, and it will work in SLI.
