Twitch Streaming PC build guide.
So you want to stream on Twitch but have noticed a huge performance impact on your games. Affecting your stream quality and viewer experience. How do you combat this? Do you downscale your stream quality? Do you play not so demanding games? No, refactor your whole streaming setup onto a separate Streaming PC to stream at the highest quality and gain viewers.
It’s no secret the most popular Twitch streamers have a separate streaming PC or server to allow them to stream at the highest quality without impacting their game performance. So what do you factor into your streaming PC? Well, the task of encoding is extremely CPU intensive so we need a powerful CPU, I would recommend 8 cores minimum. But you need to make sure your CPU is not being bottlenecked by the motherboard so that would need to top of the line as well say $200 should be enough. The last component you will need to buy is a capture card, HDMI recommended. Any capture card should do just as long as it can handle what your GPU is outputting.
What about graphics card? Don’t need anything like a high priced AMD Vega, Unless your CPU doesn’t have onboard graphics just spend $30 for a GPU to access the machine. Remeber All you will be doing on this computer is encoding and maybe running a twitch bot.
Pre-built steaming PC
Here I have built what is a decent Streaming PC for anyone to use, the 8 core processor will be capable of encoding 1440P 60fps game footage no problem. With a water cooler, this CPU should overclock easily to 4.0GHz. The 1TB hard drive will be able to store your footage if you happen to want to upload to youtube afterward. While the memory is slow, it doesn’t have to move much, video encoding will need 30Mb/s tops.

The benefits of a Streaming PC on twitch are so vast it wouldn’t be viable to list them all in this blog, but you can ask many of the twitch streamers who do use streaming PCs. One of my favourate streamers is ONSCREEN, his stream is here: https://www.twitch.tv/onscreen
This PC is really not good for anything other than what it was built for, Streaming and video encoding. You may be able to use it as a server while you are not streaming, how ever the length of time it will be down encoding will not be of benefit.
