nVidia builds its own chipset
There have long been rumors on the net that nVidia is planning to develop its own chipset with integrated graphics. These rumors are now growing after a product with an Nvidia chipset was found on the Asus roadmap.
The chipset is said to contain a GeForce version in addition to a North and Southbridge. The future board will probably support PC133 and/or DDR RAM, it is intended to support Intel and AMD CPUs. There is currently no official statement from nVidia. In my opinion, boards with integrated GeForce would sell better than boards with e.g. S3 graphics.
