So i been streaming to twitch for a bit, using my gaming rig, my loop decided to leak last night and killed my stream (i dont stream games, i stream other content 24/7) and got me thinking i should organise a proper dedicated rig.
I have at hand a i52500 (non k iirc but i think i could push it a bit) 3 times as much old ddr3 floating around as id ever need and even my old gtx1080 (i think still works) that has a full cover block on it. I am going to have to source a PSU, i cant find a suitable one for the gtx1080 lying around, i kinda don't want to waste time/money if this is never going to work. I am on a huge budget otherwise id just go buy a whole new setup and wouldn't even consider the old junk i have. Im going to go into debt buying a new system if i have to so id rather avoid. This stream is essentially my income now so its important, i don't want to lose my user base or upset my subs with downtime.

Currently i run 6 ip cams (2k) and one 1080p usb webcam and stream at 1440p, but id say 1080 would be fine given the image quality (or lack there of!) from the cheapo security cams. I run only 4 in scene at once but i run the ip feeds (as a vlc source) active even when not displayed because i run into issues when a new feed comes into scene. I couldn't run the RTSP sources direct into OBS (or other programs, so its likely a limitation with cheap cams, yes i know they're junk, its all i can afford right now ) without strange issues as well, hence going through VLC.

I have noticed on my main rig ( 5900x+3080ti with the CPU pushed very hard because all custom loop) sometimes OBS says up to 20% (hardware vs software encoding didn't seem to change anything) cpu usage of late, in the past it did seem to be less but maybe thats things like images or web sources i have added? Not new to computers (think 35+ years not new) but totally newb at streaming, as in ive been doing it maybe 2 months.

Thanks in advance for any help, i have googles for answers already but most results are relating to streaming games and/or using capture cards and such and don't really apply to my use case scenario, hence why i thought best to come here!
