We have one CDC CD4680, and we are very happy with the system, after
some initial problems (We've triggered a bug in the floating chip).

The system is really fast, and runs reliably. We don't experience
poor network performance, are you sure your network is ok?
(be sure you don't run EP/IX 1.2.1 which has some trouble with YP)

We experienced some failures with the CPU Board, but they were all 
related to heavy board swapping, during the search for the floating
point chip bug. 

CDC's support is very good, hardware as well as software.

Sincerely,
Klaus Steinberger
