Just spotted this bit of Info over at the TechReport.
Nvidia has confirmed that efforts to optimize the nForce system platform for GeForce graphics will only improve performance with nForce3 and newer chipsets in combination with GeForce FX and newer graphics products. We've already documented the performance advantage associated with pairing a GeForce FX 5950 Ultra with an nForce3 250Gb, and new GeForce 6800 series graphics cards should see a performance boost, as well. However, older nForce2 and GeForce4 products won't benefit from NVIDIA's platform-dependent graphics optimizations.
