Now that the prices have come way down on the Skylake Xeon processors, I was wondering if anyone has tried to install one in their 5K iMac. There are many tutorials on how to upgrade them from a Core i5 to an i7, but there is no information on attempts to upgrade to a Xeon from the same family. I have read that this can be done with some of the older iMacs and the Xeons from the same family that the i7 is from. The corresponding process that fits within the specifications is the Xeon E3-1275v5. It is 80 watts, which is below the 95 that is necessary for the 4.0Ghz i7, and also has the built-in Intel graphics like the i7. I've seen the 1275v5 on sale for about $140 and figured that someone must have tried this. If so, please let me know, and then I will chose between that or upgrading an older Mac Pro.
