Best Buy briefly listed a 27" iMac with 32GB memory and 7th Gen i7 and 32GB memory for $3199. If this is the real deal, it is a Kaby Lake processor which might offer 'up to 20% performance increase" over the current Skylake chips. Also, I think that's the end of a dedicated GPU as the integrated one in Kaby might be robust enough to power the 5k screen, handle 4k encoding and decoding and perhaps we can finally get 4k content to our iMacs (or at least the people with the new iMac). Real world performance: we'll see. I suspect this rumor is true and we'll see the new iMacs announced next week and actually shipping in November.
