If you have configured gimp to pick up your monitor profile the gamma
does not matter. So a mac user with a gamma of 1.8 and you with 2.8
will experience the same visual image, if both of you have
colormanaged applications. For non color managed application the
difference will be huge.

Don't believe all this gamma tests, I think that topic have been
discussed here before.
