How many times on here have people posted about updating drivers from either nVidia or ATi and having blank screens on boot up, or other weird issues not in 3D, and they had to revert to older drivers.

That kind of stuff is not acceptable in any kind of business. Whether it be mission critical or not. Time is money in the commercial world, and the more time your IT guys take to get your display setup up and running again - the more it costs you.

There is also the fact that the Matrox software in general is far more powerful in what you can do with those displays.
