So I have been doing some benchmarking on Geekbench 3 with my new iMac. I built it on Apple's site with the i7-6700k. As I was searching other 17,1 iMacs I noticed a number of iMacs with a much higher multicore score and saw they were equipped with the Intel Core i7-5930K 6-core processor. Here is the link to one of these builds: https://browser.primatelabs.com/geekbench3/4173137 I am very interested in upgrading to this processor but I have found nothing on the web about performing this upgrade. I was hoping someone on MR could shed some light on this apparent possibility. Also, these setups apparently use 2133 MHz RAM which is different from the 1867MHz stockies. Thanks!
