Question / Help Pixely When Streaming

[surexitnigra]

Hello Everyone, Ive been livestreaming for a while, and irritates me that my livestream is pixely when moving (in all games - League of Legends, GMOD, ETC.) This has been an issue and I haven't found a fix yet, so, I would like to ask for help. I have alright internet, and an outstanding pc (can stream 1080p 3500bitrate without an issue).
Internet Speed:
54.81 Megabits Download
11.58 Megabits Upload
This is from what I have compared to other streamers, more than what is naturally needed.

PC Specs:
Intel(R) Core(TM) i7-4820K CPU @ 3.70GHz
NVIDIA GeForce GTX 770
RAM: 16GB (4 X 4GB) Quad Channel DDR3 at 1600MHz
HardDrive: 3TB 7200 RPM SATA 6Gb/s

My Current Obs Settings:
Bitrate: 3500 - Buffer Size 3500
(Use CBR) Quality Balance: 10
1920x1080 Stream - No Downscale
40 FPS
x264 Preset - VeryFast

I average 35% CPU usage when streaming League Of Legends on these settings. I have also tried a 720x1080 downscale on 60fps with varied bitrates, but nothing seems right. Any help would be awesome, I have a highlight on my twitch (GMOD Highlight) : http://www.twitch.tv/godstatus888 if that helps you understand my issue.

With a good CPU like this one you could try lowering the x264 Preset to gain better quality, although your league of legends records on twitch already look pretty crisp imho.
