Interesting update...there are several studies that seem to imply the 955s run a little toasty.
No problems were encountered in the tests I'm aware of, but apparently the 955 Extremes seem to be available/unavailable at various times on Dell's site.
...maybe availability of the chips isn't up to full capacity either...
Dual dual core Opterons sure aren't a bad system either. My "State of the art as of NAB 2005" dual single-core Opteron system has been great as well...though more is always better.
