The K version allows you to overclock the CPU speed, so it tends to appeal to gamers and, naturally, overclocker enthusiasts opposed to business users. I overclock my i7-4770K not long after I got it over a year ago just for fun. This one is for my wife. She isn’t a gamer, so I wanted to make sure I didn’t push the stability. The 4790K PC beats my overclocked system by a clear margin.
This CPU is fast and stable. I have a closed-loop water cooler on it and the temperature is not an issue at idle or under load. Its about 30 Celsius idling and around 40 Celsius under load.
None. It rocks!

Works great for most daily use. No issues until I added a processor controlled monitor.
Read some of the other reviews, this thing has a history of heating issues.
Once I started pushing some higher sustained work load (80% sustained over 20 minutes) it now rockets into 90+ Celsius. Research shows there is a common defect with the heat transfer to the top of the chip causing thermal throttling and shutdowns.
I am currently working with Intel to have mine replaced as some newer batches do not exhibit the same issues.
