Today in the MacNN forums Dedicated MacNNer "ClaraT" reported that their 6 year old MacBook is starting to have intermittent graphics issues where their screen will go black and is now contemplating getting a new system, but is looking for advice on what to buy; a MacBook Pro or MacBook Air. Yesterday Senior User "mkerr64" was considering upgrading the graphics card in their Mac Pro and is wondering if the PSU they have will be powerful enough.
