I am trying to build a new streaming PC (from scratch) for a long-time streamer with a really old configuration.

Basic needs are:

  • Fluid encoding at 1080p 60fps (8+ hours per day!)
  • Gaming at 1080p 144hz for any game

I am quite confused with CPU choice. Is more cores a good thing for live video encoding? As money is not an issue, we could very well go for i9-7980xe cpu, but how worth is it? As for GPU, we thought about:

  • Titan V
  • 2x 1080Ti SLI
  • Single 1080Ti

An important concern is that is must be relatively simple to setup (like we don't want any SLI bug or whatever). So I'm thinking single 1080Ti should be enough?

Also, bonus questions if you have time:

What are your thoughts on RAM frequency? What should we aim for ?
What is a good, big, solid, dust proof case on the market?

Thanks a lot in advance for your help

  • Wow, money really isn't an issue with those rough specs! Are you planning to use software encoding or NVEC? I'm assuming you want to run everything off a single computer not some capture card setup; have you considered something along these lines though with a type-1 hypervisor, with one guest running the gaming and one the streaming, or is that not something you'd like? – JMY1000 Jan 2 '18 at 17:48
  • Regarding CPU and memory: i9-7980xe if money isn't an issue since you'll want both strong single threaded and multi-threaded performance, faster is better for money. Case is largely personal preference; What size are you looking at? Do you want liquid cooling? Window, acrylic or glass? – JMY1000 Jan 2 '18 at 17:49
  • You may be getting units mixed up. "1080p 144hz" are display specifications. If that's what you meant, all is well, but you may have missed/meant FPS (frames per second) instead. A 144 Hz monitor can update 144 times a second, but if your game is playing at 60 fps, what you see will only update 60 times per second. Vice versa, a 30 Hz monitor can only update 30 times per second, so even if your game is playing at 60 fps you'll still only get 30 updates per second. – ArtOfCode Jan 2 '18 at 23:47
  • @ArtOfCode I think it's reasonable to assume that with this kind of budget, he's got a Freesync/Gsync monitor and wants the horses to drive it to it's utmost capacity. Nothing wrong with using display specifications to define that–Hz is typically used to define monitor refresh rate rather than game refresh rate, but they're both just rate measurements, and 1080p 144FPS is the same thing really. – JMY1000 Jan 3 '18 at 4:48
  • @JMY1000 Sure, it's a minor distinction, either works, it's just customary to use the two different units to describe two different measurements. – ArtOfCode Jan 3 '18 at 16:14

To let you know what we went for:

We went for i9-7920 with single 1080ti. 3000Mhz RAM Inside a cosmos 700p

  • How much RAM? Other components? Total system price? Did you decide to go with a software encode or NVENC? – JMY1000 Jan 16 '18 at 18:12
  • 16go of RAM. AIO kraken x62 cooling. Total sp is about 4000 euros. I think it's software encoding? but not sure. – Benjamin H Jan 17 '18 at 10:05

    Can you explain why you chose these parts? Your explanations might help someone in a similar situation. – Cfinley Jan 17 '18 at 17:22
  • As I said in an other comment, we went with a professional PC builder. So I'm unaware why he made these choices in the end. – Benjamin H Jan 18 '18 at 10:47
  • Ah yes, "professional" PC builder puts 16GB of RAM in this kind of machine, classic. Probably even in dual-channel. – user13807 Apr 6 at 11:31
