Ok so i have two issues i need help with if you can do only one or both or none at all it's fine.

1.)

I am going to be running a dual stream setup. The kicker is i have a 144hz main monitor and i cannot find a capture card that takes display port. Is there a work around? like splitting a Display port to a HDMI (to the capture card) and display port(Monitor)? I am looking for the best performance ie 1080p 60fps.

2.)

I also need audio to this streaming computer and my gaming computer. I do know there are guides for other people on the forums, i just want an exact parts list and explanation on which of the parts i need so i can understand and ask questions if needed..

Thank you!
 
Does your monitor only have displayport input? What about dual-link DVI? The only monitors I've heard of with just a displayport input are GSync monitors, and I'm not sure that capture cards can alter their capture rate to keep up with GSync.

There are plenty of capture cards that can do 1080p60, but if you send 1080p144 to your main monitor and duplicate your screen and send 1080p60 to your capture card, in the past it always made your 1080p144 look like 1080p60. Not sure that they fixed that. This could be a problem for you even if you can switch to dual-link DVI input.

There are not plenty of displayport capture cards that don't do a conversion to single-link DVI/HDMI first (i.e a Displayport 1.2 input capable capture card). I know of two:

http://www.datapath.co.uk/products/video-capture-cards/visionsc-range/new-visionsc-dp2 (which costs US$1900)

and

http://www.unigraf.fi/products/video-capture-boards/ufg-07-hsdp (not sure of price, I expect it to be higher than the Datapath one though) Edit: This is a DP 1.1 board, which won't work. I thought there was another 1.2 board (but super expensive) but I can't find it any more.

I haven't heard how they work with G-Sync. I did read this though: https://www.reddit.com/r/Twitch/comments/36obz8/144hz_monitor_display_port_60hz_limited_capture


As for audio, I just use a Y-Splitter on my front left and front right and plug that in my capture computer's sound card's line in. I suspect more serious streamers use a sound mixer of some sort. A search of these forums will reveal options. For the microphones, I use two mics, one for my capture computer that is always on with the noise gate enabled, the other is connected to my gaming computer and I use push to talk. I like simplicity.

Yes it does have DL-DVI and i do plan on making a mixer setup of some sort. have any dvi options?
 
I thought quite a few people already do the Output 60hz to Capture Card and 144hz to monitor setup on nvidia cards. (AMD is a problem I think) So need for a splitter or passthrough, just clone the output and configure in the nvidia control panel.
But I can only say what I heard of, as I have no 144hz display to test this with.

Do you or anyone else know of a capture card for DL-DVI That is not upwards of $1,500 lol. Also would a displayport from the pc split into two (So single display port to Two ports). Then have a display port to hdmi adapter in one slot (Running to capture card) and regular display port in the other (Monitor) Would this work or be possible?
 
None that can do 1080p144. They're all super expensive. If you will only send 1080p60 to the capture card, there are a lot of options, here's a good current thread on it: https://obsproject.com/forum/threads/capture-card-what-to-buy.36203

But if you have to do a splitter, then the framerate sent to each device will be identical. You need to do two displays to do one at 144Hz and the other at 60Hz (as in the reddit post linked above).
