Athlon Nforce 4 IGP emerges
 

C51G Northbridge will feature the soon to be introduced NV44 graphic card. NV44 desktop version will end up as 6600TC (Turbo cache) and I guess that Nvidia will use turbo cache marchitecture to use system memory more efficiently than before.

Nvidia also says that its chipset is designed for UMA (Unified Memory mArchitecture), which clearly indicates that Nvidia will use the same memory for system and graphic tasks.
