Question / Help Help optimizing my stream.

Dear fellow OBS users,

I would like to get help with the following situation, I have been streaming on and off for a couple of weeks now and whilest I'm still configuring the best settings I still don't feel like its enjoyable so I decided to see if any of you can help me out.
I'll list my specs and current settings under here:

Intel i5 3470 @ 3.2ghz (with HT 3.6ghz)
ATI HD 6750 (buying a 7870 soon) @700mhz core clock and 1150mhz memory clock
8GB corsair vengeance ram @ 1600 mhz

Internet speeds:


Current settings:
Quality: 8
Max Bitrate: 3000
Buffer Size: 3000
Server: Global load balancing service
Audio Bitrate: 128
Minimize Network Impact: ☑
Downscale: 1.50 (1120x700)
FPS: 45
Use Multithread Optimization: ☑
Priority of proces: Normal
x264 CPU Preset: Veryfast

This was a stream I did last (don't mind the title) on black ops 2 in my native res (1680x1050) with no downscale and 10 quality:
http://nl.twitch.tv/mella7/b/381397927

As you see it is quite watchable but it sometimes gets fuzzy and I would like to fix that, If streaming in 1050 without downscale is not possible I wouldn't mind going to 1120x700 which is 1.5 downscaled

Now, I don't get bad fps but it somehow doesn't feel as normal as when off stream, it feels somehow sluggish especially when playing fps games where I use my mouse.
The CPU also skyrockets up to 100% when streaming, the only way I found that not happening was by putting it on ultrafast which eats my bandwith and I don't think I would have enough to run a stream frame dropping free ( I have unlimited monthly)

Games I've played during stream:

World of Warcraft
Fifa 13
Call of Duty: Black Ops II

I would like some assistance on what settings are best for me to use and thanks in advance.

even when downscaled I still have the issue on having 100% cpu, how do I post a log file?

Is this the correct file? this is from the linked video:

You should select a nearby Twitch server rather than a random one.

I tried that and I had more frames dropping then when using the global load service, But how are the settings? can they be better and make it better for me to stream?
