I've had my Mac Pro for 5 years now, and for some reason I've not until recently been thinking about upgrading. So far I've ordered some new RAM, and am contemplating whether or not to update to 10.6 (I'm currently running 10.5.8) I know.. My Mac is years behind, and 10.6 came out a long time ago. I think my wake up call was not being able to recognize my iphone 5, because the operating system was too old to update to the current version of iTunes.. Anyway, is it worth upgrading to 10.6? I'm running CS3 and FCP7 and don't want to risk any problems with them.
