C51G NVIDIA's integrated graphics chipset?
It looks like NVIDIA is developing an integrated graphics chipset aimed at low-end Athlon 64 systems.
Dubbed C51G, the two-part chipset apparently sports PCI Express, Serial ATA II RAID, Gigabit Ethernet, and a mysterious new integrated graphics core. When NVIDIA launched the GeForce 6 architecture, they claimed it would scale all the way down to integrated graphics chipsets. With C51G, that may finally happen.
