Question / Help Cpu to weak for 1080p?

[chrille47]

Yo!

So im trying to stream wow. When i stand still is everything fine but as soon as i move it starts to show pixels. Bitrate i have on 3000. But if i change from "veryfast" to "Faster or Fast" it becomes way better. Problem there is i get lagspikes instead. So im just wondering since i have a pretty much a beast computer i should be able to stream in 1080p good quality without lagspikes or pixels. I've check the usage of cpu and gpu during stream and playing. When i im at "Veryfast" usage is fine on both. As soon as i switch to "Faster of fast" cpu usage goes up to 100% usage while gpu still stays at 20-50% usage. So im wondering with my cpu shouldnt it be able to stream this or is the cpu to weak?

My specs:

Gpu: 780ti 3gb minne OC
CPU: I5 4670k inte O'C
ram: 16gb ram 1600mhz
Psu: 700w
OS: Windows 8.1 64-bit

Internet speed:
Download - 112mbps
Upload - 11.22mbps

Thanks!

Well to do 1080p 30FPS @ veryfast or faster, you should have at least the 4790k. I have the i7 5820K @ 4,5GHz, this is a sixcore with hyperthreading. 1080p 60FPS takes up to 55% CPU-load alone. If you really want to go balls deep - get Intel 8-core CPU, xeon or i7 5960X. This will cost you around 1000$ but thats the only way to do really fancy stuff.

Yeh, the i5 series from intel aren't really made for these kind of processor heavy tasks. It can do 720p @ 30 - 45 FPS perfectly fine though, I used to have an i5 3570k, and those settings worked great.
