So, "Montag", have you decided on what you are going to do with this machine? It will be interesting to hear how your performance changes. If you already own the machine, can you do an Xbench test: http://xbench.com/ before and after, just to see roughly what the performance boost was? Since this takes *all* aspects of the system into account, it won't be the best judge, but will still be interesting for sure.
