Thanks Claus thats good news!
I'm having a reputable vendor build the box and test it for me before
delivering. The bottom line of your message, did you mean 'should be not a
problem'? I wonder what the main reason for your improvement, your ram was
increased by a factor of 2, but 4 way opteron vs 4 way woodcrest performance
must not be that significant.
