What do I upgrade?

Hey guys I built this PC about a year ago. I did not know too much about pc parts so, I may have made some mistakes. I discovered this site and Youtube channel recently and was hoping you guys could help me out. I don't really want to do a full upgrade but maybe just what is necessary. I use this system for gaming.

Here is my parts list:

Processor:
AMD Phenom II X6 1075T

Graphics:
NVIDIA GeForce GTX 550 Ti

Memory:
8gb G. Skillz 1333mhz

Case(came with PSU):
COOLER MASTER HAF 912 ( /W 500W PSU)

Cooling:
ZALMAN CNPS10X Performa 120mm Long life CPU Cooler

and a couple of stock fans

Storage:
500gb 7200rpm something dont remember what. 

Thanks

an easy thing to add to breath more life into a gaming rig, get urself a SSD for your OS and turn that mechanical to your storage for your games/programs and steam.

Upgrade your graphic card and overclock your CPU

^

Agreed.

is it still possible to overclock it since its not a black edition?

bump

I'd just bump up the graphics card,

an ssd isnt a necessity when you're gaming

A lot of you are talking about the graphics card. What could I get thats not ridiculously priced?

Well, how much are you willing to spend on a GPU alone?
