Streaming Dota2/Diablo3 with core i5 3570k [vs i7 3770 (non k)]

[jihtu]

Hi

I recently had my internet upgraded and want to try streaming for the new season 12 start of Diablo3.

I have tried streaming dota2 @ 720p and I found that my CPU running at 100%, my dota2 game was lagging as well as the stream. As soon as I dialed down the dota2 graphics details from high to normal, the lagging subsided on both stream and game - but who wants to game with crappy details?
This leads me to believe that the bottleneck is the CPU and would like to know if there is a fix for that.
My specs are below:

core i5 3570k With cooler master 212 cooler
gigabyte z77-d3h motherboard
8gb (2x4gb) Corsair Vengence Black 1600 RAM
AMD RX470 4GB Saphire Nito+ GFX
EVGA 650W PSU
Samsung Evo 850 - 256gb ssd
2x 23" 1920*1080 monitors
(I want to be able to stream and chat to the viewers)


Possible solutions:

1) I have the opportunity to swap my 3570k for a 3770 (non k) - would this solve the problem?
2) Would overclocking my 3570k to 4ghz or even 4.2ghz be a better option?

any advice?

You would want the extra threads from the I7 for better streaming performance. Maybe consider getting an I7 K model.

unfortunately the 3770k is not available - found this guy that wants to swap.
so my question is will the 3770 give me better performance than the 3570k @ 4.0-4.2ghz?
I tried to google this, but I cannot find an answer.

With that cooler you should hit 4.4ghz minimum easily

So I overclocked my CPU to 4.4GHZ and this was sufficient to stream!
YAY, problem fixed.
