Computer part upgrades help

[Plumss]

Hey Guys, I'm deciding to upgrade my pc again to make it better for gaming and editing.
Right now I'm only getting around 80 fps in cs:go and its the main thing I want to change.
Also I'm only getting around 30 fps in ArmA 3.

I tried to make a pcpartpicker for my current build, but couldn't find some of the parts. This computer is a home computer from around 2010ish, that I only upgraded the power supply and graphics card on.
Here's the pcpartspicker: http://pcpartpicker.com/list/T2Yy4C
I was wanting to upgrade my CPU and get some more Ram, but I'm assuming that I would need a new motherboard. Also, I have 4x2gb sticks of ram and am wanting at least 16gb,

You know way more about this stuff than I do, so hopefully you can make the right calls for what I want.

I made a thread about my build a few months ago, and the awesome person gave me these suggestions after we talked a bit:

CPU: Intel Core i5-6500 3.2GHz Quad-Core Processor ($197.99 @ SuperBiiz)
Motherboard: Gigabyte GA-B150M-DS3H Micro ATX LGA1151 Motherboard ($56.98 @ Newegg)
Memory: Kingston HyperX Fury Black 8GB (2 x 4GB) DDR4-2133 Memory ($31.99 @ Newegg)
Total: $286.96

I want an upgrade from that ram to 16gb, and have heard mixed things about Micro motherboards.

Thanks for all the help!
