My settings at the moment are at quality 10, bitrate/buffer at 1100 and 1200 respectively and set to 40 FPS. Resolution down-scaled to 1.5 (1066x900). My native monitor resolution is 1600x900.

*One more thing, I'm a bit of an idiot when it comes to streaming, how would I be able to stream on 720p resolution etc? When I am live, twitch gives me this 600p+ quality. People have always talked about the 1280x720 as 720p and I'm always confused because of my 1600x900 resolution

you can only downscale from your base resolution since you got an 16:10 monitor you wont be able to use 1280x720 (16:9) im note sure what resolution 1.25x downscale is or 1.5 with your base resolution but whatever is the closest to 720p ;D usually 1.5 downscale and 30-60fps should be no problem with that cpu depending on what game you are playing

He is using a 16:9 monitor.
What version of OBS are you using?
You could probably get away with 1500 bitrate on CBR and changing FPS to 30.

Do update OBS. You're a few versions back, now. :)

I'd definitely see if you could run at 1500kbps bitrate (I prefer VBR myself). Also, drop the quality to 8. It's a good tradeoff between static-image and fast-action. If you play FPS games, you may want it lower. Stuff like Super Crate Box, you can get away with 10.

1600x900 is '900p'. It's a throwback to TV 'standards'. Personally, I'd recommend using the 1.5 downscale instead (which will give you 600p); you CAN force a scale to 720p (as you are in 16:9 aspect ratio) but it will require more work on your CPU's part to do the downsampling. Going with a full-step (1.5, 2.0, etc) is generally 'lighter' on the CPU's workload. And many people won't even really see the difference between 600p and 720p as more than just a number.

With your limited upload, the 600p stream really is a better choice though. It'll look better than the 720p, smoother, and would be what I'd go with, with the hardware you have. (If I was stuck on 2mbps total, for example, I'd probably run a 2 downscale from 1920x1080 to 540p (960x540) to help keep bandwidth needs down.)

I have the same question as well. I'm new to streaming. What settings should I be running?

Internet Speed

Download Speed: 3926 kbps
Upload Speed: 4188 kbps
Latency: 20 ms

PC Specs

OS: Windows 7 Home Premium 64-bit, Motherboard: ASUS P7P55D, CPU: Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz (4 CPUs), ~3.2GHz RAM: 6GB, Graphics Card: NVIDIA GeForce GTX 460, Monitor: ASUS VH242H

For the video settings in OBS I have it set to resolution downscale: 1.5 1280x720 FPS: 30. I dont know what I should put in the encoding settings. Any help would be greatly appreciated. Thank you for your time.

With over 4mbps upload? Is that a speedtest.net result (known to be skewed by many ISPs, who 'un-cap' known speedtest sites, but still limit regular usage) or a real-world tester like http://testmy.net/upload ?

Real-world, I'd run that at 3000kbps and 3000 buffer; allows you some margin for game-throughput, but should be more than enough for a 720p stream. Probably could even bump to 60fps (though you'd need to test this out) for smoother gameplay. I still highly recommend setting Quality to 8; it's a good tradeoff between fast-motion coping and image fidelity. Still keep the Veryfast encoding preset, and I prefer keeping mine set to Above Normal process priority (helps cut down on frame droppage during heavy action scenes).

I used http://speedtest.connectmi.org/ to test my connection speed. I'll try your link. I used the link you provided and my result for upload was, "Your Speed :: 3.7 Mbps". I selected a 6MB upload file size if that makes a difference.

I'll try out those settings you suggested. Thanks for the help. I'll post back here if I run into any trouble.

Ok, I tried those settings and I'm dropping frames. Here is the log:

I adjusted some settings tonight, then I did a test stream for almost 3 hours and there were 0 dropped frames. So Im assuming there were no problems with the stream then? I'll do another test stream tomorrow and see how it goes then.
