Well...what other chipset provider is there for the Woodcrest? Unless 
you want to point the extra power needed for FB-DIMM solutions and thus 
extra cooling I suppose...

The Korean portal also got very good performance figures (better than 
their Opteron boxes) from the Woodcrest boxes. It was big news for IT in 
Korea because the portal was exclusively using AMD Opteron.

If you do not get any problems at all with your Supermicro board and 
Woodcrest then by all means :)
