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.
