I think the Atom processors are fairly underpowered compared with even 
an old school Celeron and certainly the Core X line?  I believe they 
have much shorter pipelines and small cache's - however, please check 
anandtech and the likes for more accurate info...

I guess it depends on your budget, but the I3's are fairly inexpensive 
and decent speeds? Probably even some slightly older boards which 
support Core2 and pickup some processor off ebay? (I was looking at some 
I3 supermicro stuff this week...)

Also remember that if you call the Dell business advisor, or your local 
supermicro salesman (and presumably the HP, etc guys) then the prices 
collapse compared with the list prices.

All the best
