Twitch streaming PC

[k1ngm4c1u51]

Hi guys

I need your help with building streaming PC and I have no idea what would be lowest but decent hardware specs for streaming 720p@60Fps. I need 2nd PC only for streaming. My current gaming PC can handle 720p@60Fps but it takes too much FPS from games like Battlefield 3+4 and my gameplay is affected a lot. So I cant afford i7 at the moment so I'm looking (maybe) for AMD 6 core or maybe i5 3570k? Budget is small so basically I need to go as cheap as possible. I'm looking for gumtree too for used PC but I don't know what would be better AMD with 6 cores or i5 3570k or something else. People suggesting to have good cpu (more cores=better) because streaming is CPU heavy and 8Gb ram. If I had to choose between i5 3570k and AMD 6 core what would be better? Is i5 2500k too low for streaming at 720p@60Fps?

Any ideas, help much appreciated.

Thanks

The general consensus is i5 3570K or greater and 8GB of RAM and your good to go, there is much more to consider though like your internet bandwidth and whether your going to stream Constant or Variable Bit Rate.

I watch Mark Purdy (Valkia) stream most days, his set up is as follows:

• Intel i7 3930K
• Gigabyte NVIDIA GTX 780
• 16GB Corsair Dominator Platinum

You could get a decent AMD graphics card ( 380X maybe?) and use OBS and turn on the OpenCL encoding. Should work like a charm without having significant effect on your CPU/RAM and not such a big hit in gaming performance either!

380X doesn't exist, does it? I've got the 380 4GB and I believe that that's the "newest" revision.

I thought that the X was the 4GB version... lol

Easy mistake to make with AMDs naming schemes

AMD 8 core cpus are a better bet for streaming than non overclockable i5s. It'll happily do 1080p 60fps on an 8320 as a dedicated streaming rig.

Do you have or know of any actual benchmarks? I've heard that the AMD 8000 series is better than i5s for streaming, but I've never seen any benchmarks to back it up

This video should give you an idea. But that's purely based off CPU performance for streaming...

Personal experience and about 10 months of research when I was building my AMD rig. I built it for streaming while playing. Sadly I then got horrible internet so the streaming dream went out the window.

I also was able to max the CPU out by streaming and playing ARMA III at 1080p@60fps (more like 30fps due to cpu usage being 99% ).

Just to give you a rough idea, the 9590 can render videos faster than a 4770k (at stock)

From the Twitch streamers that i watch most of them will have a second PC as a streaming PC.

It will take load off from there gaming PC.

It's rather silly.... Unless you want to stream in 1080p 60fps+ then yes I would aggree something x99 or x79 would be needed and a powerful gpu. But a second pc is just silly

Not really. Its silly if you're streaming something basic otherwise its nice to have a PC just running games. If you stream at the semi standard that is 720p 60fps it does put some load on your PC and you loose quite a few frames. I'd hate to stream a twitch FPS like CS:GO and get framedrops/ping spikes.

I'm quite certain though that for that basic 720p 60fps a powerful AMD gpu could handle the OPENCL calculations for that. The real problem would be the internet bandwidth

That'd still give frame drops. Also not worth it if you're trying to stream something intensive like GTA V.

Not to mention because stream archiving doesn't last forever you'd ideally be recording and streaming at the same time. With a separate PC that means you can have something recording and encoding in 60fps/1080p and then streaming the footage in 720P/60fps at the same time. No frame drops either.
