I have asked you guys before to _please_ not cloud these discussions with real
facts and data.  Here, the only way to discuss things is to make up details to
match your argument.

Much better:  in 3 months the G7 will be released at 6ghz with 6-way
super-scalar operation and 10ns memory latency,,,

then you will be arguing on vincent's level...
