The issue with NAM varies from system to system. Most systems work fine (that's how nVidia is able to ignore the problem).
The most common complaint for NF3/NF4 systems is failure to respond when you click while browsing; clicking a second time works. This also manifests as a "No internet connection" message which works when you try a second time. Could be NAM or the NIC driver, hard for a user to tell. P2P problems are probably the second most common reported problem. Distorted jpg files are another common problem, e.g. I captured this:

And my personal favorite is NSVCIP accessing my disk 1 to 3 times per second continuously; this is reported by an even smaller minority of NAM users, I am aware of only 3 complaints so this is likely a permanent feature of my system.
The changes in the 6.70 release seem to be minor and don't affect NAM or the Ethernet driver, apparently, nVidia doesn't see any problems with them in spite of the noise in their forum. The recent uproar caused by the Inquirer picking up on someone's mis-diagnosis of a disk problem as being an NF4 driver problem lets nVidia off the hook for the forseeable future as far as fixing anything...

Your best bet on a new installation is to use the 6.70 release; the installer has been updated again and seems to be working better with each release. (The programmer in charge of the installer needs to be put to work on some of the other problems now that he has gotten the installer fixed.) I simply removed the earlier NAM and all nVidia drivers and ran the 6.70 installer; none of the magic sequences involving Driver Cleaner etc. which were required for 6.53 and earlier releases - YMMV, of course.
HTML destroys the tabs in the following so try looking at the source if you're interested in seeing this in easy to read tabular format - you can see what nVidia is working on here.
