I'm planning on getting the new iMac, and I've got the configuration chosen except for the CPU. I've done a lot of research on the 7700K, and it seems to run very hot under load. It's rated for a maximum temp of 100 deg. C, and many tests have shown it to operate near that limit when pushed. I know the chip will throttle back to preserve itself, but then you lose the benefit of the rated clock speed. Also, the surrounding electronic components are subjected to the heat. I have a PC that I built a couple of years ago with an Intel 4790K (also 4 cores with hyperthreading and an 8 MB cache), and it never goes above 70 deg. C when being stress tested. My PC has two fans on the CPU heat sink (air cooled only), and three case fans. Even with all those fans, it's fairly quiet (expensive fans). I would never want a CPU to operate so close to its Tjunction limit. The iMac has a very hot chip in a small case with one fan, and that concerns me. The 7600K operates at lower temps than the 7700K, according to tests I've seen. I assume the slightly lower clock speed and lack of hyperthreading contribute to that. So here's my dilemma. I believe Logic can take advantage of hyperthreading, but I'm not planning on creating projects with dozens of tracks. So for those Logic folks out there, do you think the 7600K would do the job? I've actually used Logic on a 2009 Macbook Pro with a chip with two cores and no hyperthreading, so anything would be significantly better than that.
