I need to make a choice between upgrading my current computer or building a second dedicated streaming PC and using two PC's.

I am looking to get into Twitch.tv and youtube gaming live streaming this summer.

I am torn between upgrading my computer with a Ryzen 1700, DDR4 memory, and the Asus crosshair 6 hero motherboard and getting the EKWB monoblock and custom loop; or building a second small form factor PC with the Ryzen 1700, no custom loop, and using my current computer for my gameplay and the new Ryzen PC for live streaming.

I would prefer to do the upgrade and have one computer doing both the streaming and gaming. So my question is can a Ryzen 1700 overclocked to near 4ghz, plus 16 GB of memory, and a GTX 1070 handle 720p 60 fps live streaming on a 10-11 Mbps upload connection?

My current computer setup is good and I can play games really well, which is why I am thinking about building a second PC and using two PCs. I kinda don't want to waste the hardware. My current PC specs are:

Processor - 4790k @ 4.4 GHz
Motherboard - MSI z97 gaming 5
Memory - 32 GB 2400 mhz DDR3
Graphics card - Gigabyte GTX 1070
Power Supply - EVGA 650 watt
Storage - Samsung 960 pro, Sandisk Ultra 2, Samsung 850 Evo
Case - Corsair 780t
Cooler - Noctua NH-D14

What do you guys think? Two computers or one computer?


 
What is your actual budget, for what you want to do? The 1700 makes perfect sense, and is very capable, for what you want to do, especially at such a low resolution. Not sure the custom loop is worth the cost though.
 


my budget is in $1000 - $2000 range. Can a 1700 handle 1080p 60 fps streaming without dropped frames? I might not do the custom loop, I may just get a Kraken x62.
 


OlympusHAXXX,

In my view, it's wiser to invest in a single set of the highest quality components rather than dissipate the assets over duplication. For the last nine years, I've maintained two systems: one for 3D modeling having a high single-thread performance, and the other for simulation / analysis , and CPU rendering which used dual 4, 6, and recently 8-core Xeons. This made sense until recently when it was possible to combine these systems into a single one as workstation GPU's are now in the same 3D performance league as gaming cards. The Quadro P2000 5GB I bought a couple of weeks ago is faster than a GTX 1060 or 780 Ti.

I don't see the value in the expense of using a separate 8-core system for streaming. For one thing, the streaming can not make any meaningful use of seven of the cores and for another, it's paying for two sets of everything.

The current system is difficult to improve more than a large increment. If you're running an i7-4790K at 4.4GHz, the all important single thread performance is reasonably near the top- an i7-7700K is about the only meaningful improvement. On Passmark, the average i7-7700K has a Single-thread Mark of 2591 and the i7-4790K is second at 2529. There are other advantages to an i7-7700K especially DDR4 RAM at speeds of 2666 and NVMe drives.

To move nearer the top, consider: an i7700K / ASUS Maximus IX Apex or Hero / 2X

The current drives are very good Noctua NH-D14 may be sufficient for cooling as the power rating of the I7-7700K is lower than the 4790K.

What are using for the sound card? It might be a good time to improve that. I just added a used ASUS Essence STX PCIe sound card to the new system ($95). That is shielded, has audiophile capacitors has a 20W headphone amplifier that is the best headphone amp I've every owned and the SNR is - 124dB whereas my previous high end recording interface was 113. If you're using surreound, and would prefer to buy new, have a look at:

Creative Sound Blaster Z PCIe 116dB SNR Gaming Sound Card with 600ohm Headphone Amp and Beamforming Microphone > $106

Why not have top performance all the time and consolidate the costs into the best possible parts? If you feel the need for a separate streaming system, consider building the new parts and current used drives into a new case and power supply and add a 960 Evo and GTX 1060 to the i7-4790K system and the total cost can still be near the $2,000. The 4790K system would have a strong resale sales value as a complete, top tier gamer.

Personally I'd go with 1 PC. You'll be maintaining 2 PC's and having to upgrade both when needed. With that budget you can build a killer Ryzen rig that'll do everything you want(streaming, recording, gaming) at the same time on one rig. If you're worried about wasting the power of your current PC, once you are up and running with your new rig just sell or part out your old PC and recoup some of the cost. Let me know if you'd like to see some of my recent recording from my Ryzen rig and I'll give you a link.
 


I would like to see them.
