An overclocked 4770k can get pretty hot. If you have plenty of airflow and don't plan on overclocking too much (only about .2 or .3 Ghz), the H60 should be fine. I was OCed at 4.6Ghz on my i7 4770k with an H100i with 2 Noctua NF-F12's with a pull configuration. I was sitting at around 65-70 celsius idle (which is pretty damn hot). I was getting almost 100 celsius while running GTA 5 on maxed settings with a 980 Ti. However, I do have an NZXT H440 which does not have a lot of airflow at all. I have 6 fans in the case including the ones on the H100i, but it still does get pretty hot. I went back to 4.0Ghz for now because I feel it's just fine for me.
Nowadays, running at 4.0Ghz is just fine for gaming, the perfect, safe sweet spot. But, as games advance and become more complex in the coming years, overclocking will become much more mandatory for CPUs like the 4690k and 4770k (considering you want to play smooth at high FPS).
I would hold off until you really do need to overclock. But if you feel like you can drop money on a new 4770k because you got the 4770 for a great price, then go right ahead.
You could even sell the 4770 to help pay for the new one, of course.
An i5 4690k is adequate for gaming, but if you record you might want the extra processing power and the safety cushion of the i7 4770k for future games.

TL;DR: Overclocked 4770k's can get pretty hot. Have lots of airflow. High-end gaming today doesn't require overclocked CPUs, but they will eventually.

If your CPU is hitting 100*c often, you need to reduce your overclock, for sure. Hitting 100*c in heavy stress testing is fine, but not when you're playing games. It's technically still safe at 100*c, but if it's sitting at 100*c for a few hours while you're gaming, you should really mess around with your OC for better temperatures. My 4790k would sit at 4.8GHz, idling at 40-45*c. 70*c idle is way too hot. The airflow in the H440 isn't terrible, I have one and my temps are fine. You can take the side panel off to let the CPU and GPU breathe a bit better if need be.

4GHz isn't the "perfect sweet spot" for overclocking. Overclocking is different on every single chip, even two different 4690k's won't overclock the same. Overclocking is never "mandatory" and never will be.

OP-Depends on the rest of your specs. Do you know what you're doing when it comes to overclocking? You'll want to buy either a 4690k, or 4790k if you're going to overclock and then sell your 4770 for as much as possible. The H60 is meh. You'll be able to get a decent OC out of it.

I realize the airflow isn't terrible, but airflow is definitely one of its lacking features. And I know 70C is way too hot (which is why I stopped overclocking for now). But even at 4.4 Ghz (my BIOS doesn't let me choose 4.1-4.3), it gets pretty hot. I idle at about 40-45C now which I think is good. What do you think could cause my CPU to get too hot? Maybe I should re-seat the cooler and get some Arctic Silver.

And maybe I should start my own thread.
