This is a pretty cheap entry level gaming build I built for a friend who wanted to get into PC gaming as cheap as possible.
Most of the parts were from a computer I bought from my Cousin, which he actually bought from me a year before to make a rig for his sister but never got around to it. I bought the tower, motherboard, PSU, CPU, RAM and GPU for $90 which is about as much as he bought it from me, so I was happy.
I went to my local used computer repair shop and bought a HDD, Optical drive, VGA Adaptor, and an 8GB ram kit. I got a cheap key for Win 7 online for $20, but it was a pain.
If you noticed, I didn't use the normal AMD stock cooler. I took the slightly better cooler from my 8320 that I never used since I got a 212 EVO. It looks cooler too. I was also able to unlock a third core, but bringing it up to 4 was too unstable.
I don't have any benchmarks, but it runs the games she wants like Dragon Age and Undertale and a bit of Overwatch. Overall, it was pretty fun to build and it was cool making my old parts useful again.
Also, check out that setup, hahah. She'll be getting a new desk soon.
