Question / Help Frame rate drop using Lenovo y50 4k UHD

I have been having issues for a few weeks of tweaking OBS because I encounter frame rate drops while streaming & recording. I have to resort to asking you guys for help because this is a nuisance.

I have been recently been playing Smite, but often I play League, CSGO, and 7 Days to Die. In Smite, I averaged at around 100 fps but while streaming, I received high 70s fps. More importantly, League and 7 Days to Die is really noticeable in game play in which I experience major issues. While I play league, I get 80-140 fps but while streaming, it can decrease to 30-50 and it is really noticeable once I stream. I looked at a recording of a few minutes of game play and I do see the stuttering.

I tend to stream both at my own home (wireless) and college home (ethernet). My house has an upload speed of 4+ Mbps and college house is 5+ Mbps. Download speed is both ideally 60+ Mbps.

My laptop, Lenovo y50 4k UHD, uses Nvidia GTX 860M, i7-4700HQ CPU @ 2.40 Ghz, Intel HD Graphics 4600, 16gb of ram.
I do use the GTX 860M for OBS.

What optimal settings can I reach with this? I tried using NVENC in high quality and I can stream perfectly fine but the quality is not the same as x264. I even set bit rate to 1500 and even 2000 kb/s but still has frame rate issues. I want to stream at 720p @ 60fps without frame rate issues. Is it even possible to achieve this with Lenovo y50?

That seems kinda normal with the x264 (CPU) encoding.. Your choice is probably gonna have to either be 720p30 (or lower) or just take the quality hit from NVENC

Also, if you're streaming to Twitch then im pretty sure your keyframe interval should be set to 2
