It's far from good enough, the Intel chipsets are always superior in performance and more stable than the nVidia versions.

Intel chipset revisions sometimes yield significant performance gains, sometimes not but the nVidia boards are merely just rehashes of their old nforce5 chipset.

The only good chipset nVidia has released (relative to the competition) is the nforce 2 board, the rest have been pretty dire, only cheaper prices and lack of decent AMD boards has kept them going...
