My research online has led me to believe that the next gen Nvidia Maxwell GPUs will be released in February 2014 including the GeForce 800m series. Should I wait for the next iMac refresh/update or should I just stick with the 780m model that is currently out? I don't want to spend $2.5k right now if a newer and more powerful model could potentially come out in a month or two. Do you think that Apple will immediately release a refreshed iMac with the new GPUs or will they wait for the release of Broadwell CPUs? Also, could there be a possibility of an improved resolution monitor in the next refresh? And maybe Thunderbolt 2 even though I wouldn't be able to utilize it past the potential of first gen Thunderbolt.
