Hello Patrick

Thank you for your very detailed answer.  It is much appreciated.
As you may know, I've got 16 nodes worth of Myrinet already on order :-) :-)

What I failed to mention is that I've decided to go with the 760MPX
chipset.  I want the AMD CPUs.  And I wanted the headroom, but I'm swayed
by realities.

Yes, very cool.  For us, the nodes are compute nodes, so video is not
a factor. :-)  In fact, in order to fit Myrinet, GigE, and SCSI (on-
board SCSI is another aspect of our ServerWorks boards that I will miss)
into a 2U chassis, we may have to leave out the video cards.  :-) :-)

Thanks again,
