OK, I'm working in an environment where output to press is important, but general setup doesn't seem to be. A recent check of the four macs in our dept, reveal that none has the same RGB setup, although we all work together. Pretty sad huh! My question?

We're all using G4's with PC monitors, NEC MultiSync 1250+ models.
For our RGB setup should we be going with the mac 1.8 gamma and 5000 white point, or using PC 2.2 gamma and 6,500 white point.
