Upgrading current system

[lefse]

current system:
AMD A10-5800k 3.8 quad core
asus f2a85-m pro micro atx fm2 mobo
corsair vengeance 8gb ddr3
wd caviar blue 1tb
650w corsair enthusiast 80+ bronze cert atx
win7 64gb (have option to upgrade to 10)
using asus 24" ips 1920x1080
I use fair settings with low particle density and high view distance.

Looking to see what I can do to upgrade the current rig in the most cost effective manner.

Main concerns would be performance boost per $ when upgrading. Live in a large city with a fry's as well as all online retailers.
Looking to eventually do everything on high to ultra. May also consider games like CoD:BO3

A few questions:

- Does the rig have a descrete gpu?
- The psu is the "TX" series and how old is it?
- The ram sticks you got they low profile and on how many mhz they running? Can you give us a link of them?
- Whats the exact model of the pc case?

Dependin on the above you are looking to keep ram-psu-hdd or not and buy cpu-mobo-gpu.
