We are talking double CPU here, so it might be worthwhile to note that the architecture chosen by Intel shares bandwidth between processors, and the architecture chosen by AMD scales the bandwidth linearly with the amount of processors. Also, even apps that require massive bandwidth but where the datastreams are not predictable will suffer badly from the higher latency. All together, unless you do very specialized work such as video editing, you won't notice the difference in performance. > Intel has some really cool stuff on the horizon, but AMD's Hammer should be > here by the end of the year as well.

That means that you can address more as 4GB RAM without tricks. That should really make a difference for heavily loaded systems where you can then use RAM to offset I/O latency (database servers, news servers etc.).
