If your work does not involve commercial printing,setting it to North American General Purpose may help.
You can get increased saturation -- actually ugly colors -- if assigning a higher gammut profile to an image tagged with a lower gammut profile, e.g. assign AdobeRGB to an sRGB image.
(Note that 'Assigning' a profile gives far different results than 'Converting to' a profile.)

a profile
That's an understatement. "Assign" is really an expert feature, never to be touched unless you are 100% sure of what it actually does. In almost all cases "Convert" is what you want.
In any case, this is a very common cause for this type of problems. The difference between Photoshop and the others is that they are not color managed and will just ignore the profile - thereby showing it as if it was sRGB, even if it isn't. But Photoshop shows you what the file actually looks like with the embedded profile.
To complicate things, the new wide gamut monitors can enter into this equation in some circumstances involving untagged images or non-color managed applications.
All in all, a screenshot or two, including one showing your color settings dialog, would be very helpful. Come back if you don't know how to do that. Oh, and the name of your monitor.
