and the point is that quad CPU boards are expensive because the demand for them as anything but servers (and as servers too, really) IS ALMOST NONEXISTENT. look at all the extra costs of going from 2 to 4 CPUs on a board: you can't fit all 4 on the mainboard, so dauthercards are required, all schemes for this are proprietary. so whether or not *you* can use it is not the issue. the fact is you are greatly in the minority and you know it. think of yourself as the exception that proves the rule. b3n On Sun, 27 Apr 1997, Kory Hamzeh wrote: > > I'm not going to sit here and argue with you.
