I'm getting paid in 2 days, what should I build?

[dialgarocksful]

My purpose of this build is to render 3D models in Maya (mentalray), stream some games in 720p (480p when internet is in peak use), and rendering 720p videos. I'm fine with slow render times since I formerly used an i3-2330M to render a 1080p 15-minute video (that rendered for 1 hour). 

 

Here's the parts I already have:

- Corsair Vengeance (HP) 2x4GB

- Storages

- Case

- HD7750

To get: Seasonic M12ii-520

 

Choice A:

- i3-4170 + Asus B85M-Gamer (sell this cheapo mid-tower, get a more value cube case)

 

Choice B:

- FX-6300 + MSI 970 Gaming (I'll be adding Hyper 212 Evo + a 0.5GHz overclock along the way)
