[SOLVED] What to upgrade?

[LegoLoco45]

Howdy!
Me getting some extra cash i've decided that i'd like to upgrade my ol' game rig and get him some new superpowers or something.
Anyways, I'm currently thinking if I should get a new cpu, more ram or just get a better gpu. Probably mobo could be outdated as hell.
My build:
MOBO : GA-F2a68hm-s1
CPU: AMD Athlon X4 845 (Isn't OC'd.)
GPU: Asus rx 460 2gb OC
RAM: 2x4GB Hyperx DDR3 (I think it was 1333MHz)
HDD : An old 1TB HDD, (don't plan to upgrade)
SSD: ADATA SU 650 240GB
PSU: EVGA 430W 80+

I'm running on budget here. I'll probably be buying some used parts, but I'd like to know on what should I focus on.
Thanks in advance.
