Hello,
I have problem with OBS. When I play without streaming, game is nice smooth and my processor is running on 20%. But when I start streaming, CPU work on 100%.

Here is my log. I don't know why is my stream laggy, but I don't think because of low power of my hardware.

Sorry for bad english, I hope you understand.
Thanks.

Its because of your low power hardware. The older Core2Quad barely can run 1080p on very fast, you are trying to run it on faster even. Use very fast and you should be good to go unless you play a very cpu heavy game like BF3/Crysis or something.

Change the preset back to veryfast and downscale by 2.00. you also want to use the 64bit version if possible for little more increase in performance.

Your current bitrate is causing you to drop frames. you wanna lower that a bit also and try different twitch servers.
