Unfortunately my second PC can only do 720. You think it's smarter to just upgrade the stream PC?i would stay at a two pc setup. Streaming and gaming on the same pc will be always worse against a two pc setup because obs need gpu power too.
Both have AVX512 that might help, as x264 have started to use them on recent updates.Would a 7940x be enough with 14 cores or should I step up to the 7960x?
The original plan for the 5960x was to have one PC to stream and game from but unfortunately it was struggling with 720p streaming. I used a spare Xeon I had laying around for a streaming PC since I had all the parts. The Xeon does quite a bit better at streaming than my 3930k @4.5 GHz did so I just left it in the box. I really want one PC for all my needs.Both have AVX512 that might help, as x264 have started to use them on recent updates.
Try asm=AVX512 or asm=AVX2 or asm=AVX, but using it on unsupported CPU will instantly crash OBS when encoder starts. Most of the time, auto-detection (no "asm=") works fine.
Faster GHz speed (7940x) wins on this benchmark website.

There is a limit on how well x264 can do with too many threads. Can limit x264 threads with threads=16 or less.
Edit: your gaming pc seems better then your streaming pc. The streaming PC CPU (e5 2660 v2) is kindof slow, and is without AVX2.

Also I'm currently using Ubuntu on the streaming PC and setup an nginx server to transcode the stream which comes from the gaming PC via nvenc @25k bitrateBoth have AVX512 that might help, as x264 have started to use them on recent updates.

I've just read the gaming performance, especially at 144 hz isn't great, that's the only thing stopping me.I have a AMD 1950X and I can stream 1080p60 w/5-6k bitrate and medium/slow preset works no problem
Gaming computer uses nvenc @25k to the streaming computer over the network and the stream pc uses nginx to transcode to twitch.How are you capturing the game? With a capture card or capture device?
If using OBS in gaming computer, gaming computer can be slowed down by OBS, game capture, and encoder (NVENC). Also, streaming computer have to do something more: decode video that came from gaming computer.
Capture card (USB 3.0 or PCI-E or faster) is the best way to avoid any slowdowns on gaming computer. Be sure to get a capture card that is compatible with Linux. There is OBS-Studio for Linux. But I don't know about the limitations of g-sync and cloning mixed refresh rate. Getting to clone 1440p native and 1080p downscale for capture card might not be a problem with NVidia's "DSR" Dynamic Super Resolutions found in NVidia control panel, manage 3D settings, on newest NVidia graphics cards.
