Anyone tried streaming with 3080/3090 using Nvenc in Streamlabs?

Hi all, I have a 3090 on order and as a very small streamer I'm wanting to find out how well Streamlabs performs with a 3080 or 3090 when using Nvenc for video encoding in Streamlabs OBS.

I've a dual PC setup currently which I use with NDI Scan Converter over cat-6 with a 1080 in the desktop and a 1070 in my streaming laptop, so both are equipped with the older Nvenc chips (Turing/Ampere use the newer chip afaik). I'll admit that I'm chasing the ideal of a single PC setup with two monitors as dual PC takes up a fair bit of space.

Currently I can run at 6000 bitrate at 720p 60fps smoothly, but I really am seeking smooth 1080p at 60fps for my stream output.

I'm hoping the big bump in cuda cores in the 3080/3090 means a big bump in Nvenc encoding while streaming, I'm just hoping there's another streamer on here who can weigh in and give me an idea of what performance jump to expect!

I can always bump up the bitrate so that's not much of an issue. I stream on Facebook Gaming so no bitrate cap. I know quite a few streamers do use 900p though if on Twitch.

I know Turing and Ampere use the same encoder as I mentioned it in the original post, I'm guessing its boiling down to my 6700k being a weak link.
