The overheating issue is not resolved.
What AMD did was impose a design restriction on mobos, where the mobo must have some form of OCP, because AMD isn't ready to do it on its own. (btw, don't believe Tom had anything to do with it). So OCP will shut down your PC, if the CPU overheats. What happens to the data? gone.
Throttling is good/bad. It's one approach to the problem. There are others. The advantage is that the PC doesn't shut down. The disadvantages is that you may not know that there is a problem, and only end up cursing at your PC for running so slow! Also, it seems like the throttling may lower the maximum performance, by keeping the CPU up some 95% of the time (example).
What AMD would need to do is implement a serious standard in its MP line, so that AMD can start competing with Intel on the server level. The Athlon chip can beat a P4, especially for an app server. Then again, AMD may not be quite ready to take on Intel at that level.
