Is it possible for apple to make a silent CPU update before Q2 2015 and Broadwell? I mean, why not? If so, what CPU can they use in iMac? Intel 4790, 4930, 4960??? I am going to buy a new iMac very soon but I can wait three weeks from now if some update is coming. Apple should do a cpu update to iMac before Broadwell 2015, so they can attract new and existing customers. What do you think?
