$600 for PC upgrades?

[Guest]

I've been researching for a while mow and figured it couldn't hurt to get some ore opinions. I have some parts picked out to upgrade my PC, but I want to see what you guys would choose. I have in my current build a R7 240, AMD A8-6600k, generic 300w power supply, and a cheap mobo. I was on a tight budget when I first built it. For those wondering, I have an SSD and HDD for mass storage, along with 12gb of RAM. NO problem there, I've upgraded slowly and I am now too the graphics card, processor, mobo, and PSU. What should I do? I am starting a YouTube channel in the spring and I game a little bit at 1080p. What would you upgrade to? All and any help is appreciated!

I also could go a little over budget for an unlocked CPU and motherboard, just to squeeze a little more performance out.
