I currently have an I5-750 processor, and it just isn't cutting it for my video editing/gaming/live streaming to twitch.tv needs. I want to upgrade to something, and the reviews for it are very inconclusive from what I can tell.

A main concern that I have is that the 4770k runs hot. I currently have a tuniq 120 tower extreme fan, and would rather not upgrade to liquid cooling at this time. Based on the temperatures these processors run at, which one would give the most speed for what I could overclock it to?

Thanks!

The 3770k runs hot

Here's another subtlety you should know about, when Intel released Ivy Bridge people noticed that Ivy Bridge processors overheat quite fast once you pass 1.30 Volts on the processor, which has everything to do with the TIM / Intel Heat-spreader used. It has been widely discussed by many of you. With that in mind I was a little surprized to see that with Haswell, Intel decided to ignore the critique and applies exactly the same methodology.

Overclocking wise Intel did open up a set of new overclocking options. But the end result remains similar to Ivy Bridge. Now, overall we do have to say that the ease of overclocking with K model 4770 processors remains impressive. You'll reach +4.5 GHz real fast. But sure, be advised and get some proper cooling to achieve and maintain acceptable temperatures. The bottom line is that once you pass 1.30 Volts on the processor, heat becomes an issue real fast.

I tested the Tuniq Tower 120 Extreme from my i7-950 build with the 4770k. It out performs my current h80i by a few degrees. If you plan for a high overclock stick with the 3770k. 80C is pretty common, even at stock voltage, with the 4770k. It would require a liquid cooler exceeding $100 or a $80 air cooler to reach 4.5Ghz

From what I gather I have an average chip, some people are able to pull 4.5Ghz at much lower voltages.

Corsair h80i 4.3 Ghz @ 1.237v max temp 84C (AIDA64)
Tuniq Tower 120 4.3Ghz @ 1.250v max temp 79C (AIDA64)

Tuniq Tower 120 i7-950 @ 3.85Ghz 1.175 volts under load 67C

I'm not too sure if I necessarily plan on a high overclock, the higher the better of course, but let's just assume I plan on an average overclock. Would the 4770k still perform better and at lower temps given the same overclock as the 3770k?

Looks like the 4770k is the best option for me then, thanks everyone!
