What should I upgrade next?

This is my gaming rig, I need an idea of what to upgrade next.

I'm not big on overclocking.

Case: cooler master haf 932

Depends on what you wanna do.  What type of games do you play?  What settings do you wanna hit?  What do you feel is holding you back?  Why do you wanna upgrade, or do you just feel like upgrading for the hell of it.

Well, I'd upgrade the GPU. But to do that you may need a new PSU. How much money you have to spend?

I play a mix of games likePrison Architect, Space engineers, Far Cry 3, skyrim, arma 3.

I'm fine with hitting a high Graphics (not Ultra High)

I wanna lessen my overall load times, but I'm not sure what to upgrade to get the job done.

$500

I'm using a Antec Basiq Plus 550W 80+ Certified

Alright. Well get a new GPU then. 

How much do you have to spend?

That's what I'm thinking at the moment.

I'd get a new GPU: R9 290X

+1

However, that PSU makes me want to grind my teeth.

upgrade your cpu first. fx6300 or 8350. or if you want intel pick an i5 or i7

I'd like to stay with amd.

also I plan on getting a better psu (gold or Platinum)

gpu, it will give you most in your game performance.
