Considering upgrading my GPU

I am currently considering upgrading my graphics card in my PC. I bought a pretty average prebuilt from best buy. It's an Asus M32(K30AD_M31AD_M1AD_M32AD).

I've been reading around about graphics cards and I know mine isn't a great one, so I'm considering upgrading, but would like to know the benefits I would get out of it. Also would I have to increase my power source depending on the card, and if anyone could name a few graphics card in specific that would be the best bang for my buck, I would greatly appreciate that.
I mostly use my computer to play FPS games, (H1Z1, CS:GO, Borderlands, Call of Duty) A lot of the times I will stream and record my gameplay for the fun of it and so I could go back and watch any exciting things that may of happened in my gameplay.
I usually monitor my CPU's performance while doing these task and my CPU usually ranges from 85-100% while streaming and recording in 1080p at 60fps.
Sometimes I will downscale my resolution to about 720p and my CPU will be at about 50-70%
Pretty much I am wondering how and what benefits will I have if I upgrade my graphics card, and if I do upgrade my graphics card will it take some stress off my CPU?

That just about scratches getting a GTX 970, an adequate PSU will cost $50 or more. You'd be lucky to get a GTX 970 for less than $320. That leaves the GTX 960 (@$200) or comparable AMD card such as the R9 270/280. I'm not a follower of AMD's offerings and don't have a positive opinion of them.
