I have had no problems with my MSI board based on the Nforce 4. I've had it since about September of 2005. The only thing that's come close to a problem was having to disable NCQ on my sata drive because windows didn't get past the loading screen with it enabled. I haven't tried it with the newer Nvidia drivers, it may work now. So far my NF4 based motherboard has been great. Only downside that I can see is the fact that the NF4 requires more cooling than older Nforce chipsets.
