Sure, as long as the output file format doesn't store the (incorrect)
gamma information. I think only png stores it. You know what your
monitor gamma is and if the image looks good on screen then all is well.

Remember to adjust your monitor brightness and contrast too.

When publishing your images I would recommend using gamma 2.2 in the
image file. It's the standard agreed by such small companies like
Microsoft, HP, Adobe and Corel. Just apply your_gamma/2.2 correction
to the image in an image editor (Paint Shop Pro, Image Ready, etc.).
