The C51, an advanced PCI-Ex chipset for the K8 platform, is set to be released
about a month from now. Another chipset, the C60, for Intel platforms, is set to be released soon after. Newer motherboards have been lacking in support from nVidia in this area, and nVidia hopes to compensate for losses on the X-Box by giving the market this. Knowing nVidia, it will likely be a big performer with lots of features. I've yet to see a disapointing (overall) nVidia chipset.
