Question / Help Nvenc max settings?

Hey all,
This is my first time with a 2 pc set up and I am messing about with both Quicksync/Nvenc,
at the moment it looks like Nvenc is best for my setup for streaming quality, my main game is H1Z1 which is very CPU intensive, and having Quicksync set to quality preset with 25k bit rate is really not looking great on stream, definitely not 720p @2500k bitrate laanczos 30fps, Maybe you could give me tips on that?

Anyway in the meantime I switched to NVENC to test that out, My results have been much better but I have set a HUGE bitrate and not sure if it's a glitch or not.
Settings:

CBR
Bitrare 150,000
Keyframe interval = 2
Preset Blueray
Profile = Main
Level = Auto
Use two pass = checked
GPU = 0
B frames = 2
Lanczos
720p 30fps

Should I change any of these? what does the GPU setting do? Bframes? Level?
Also I have messed about with bitrate starting at 50,000 which most seem to use but didnt look great so kept putting it up, 60k, 70k, 85k, 100k and it kept improving, is 150k even realistic or is there some sort of glitch?

Thankyou C3r1c3, What about gpu/bframes?

Is 150,000 bitrate just a glitch? the quality seems to be really good at that level but not sure if its unusually high and if something is wrong?

Also just to add to that, the settings on my streaming pc are:
x264
Rate control: CBR
Bitrate 3000
Use custom buffer = Unchecked
CPU preset = Faster
Profile = High
VFR = unchecked
x264 options = empty
720p 30fps
lancsoz

I5-2500s
4gb ram
standard hd 3000 internal mobo graphics

Are these settings pretty much optimised or is there anything worth changing?
The preset and bitrate are pretty much maxed out because I am unpartnered and cannot really put them up without lagging for viewers (have 12mb upload)

I didn't address the GPU number or b-frames because they are correctly set.

NVENC usually requires 2-7 times the bitrate of x264 to look as good.

As to the specs of NVENC (i.e. what is supported and what isn't), you can get that info from NVidia.

If you consider that the average professional video editor edits video at 1x-30x the bitrates you're recording at, you'll see that it's not that big of deal to record at 150,000kbps (that's only about 18MB/s), so hopefully that gives you some perspective on the issue.

As to streaming, if you want to get as many viewers as possible, consider lowering your bitrate (2000-2500 is the range we usually recommend for non-partner streamers), this way more people can watch you without buffering/pausing.
