CPU for iMac 27 , mid2017
What CPU will be better to take for my iMac 2017 which has i5-7600 now. i7-7700 or i7-7700k or i7-6600k?? About 7700k I’ve heard that it overheats because of weak cooling systems. But I’m sure that 7700 without “k” working good -but it has less power than with “k”) dilemma)) who knows how?)
