UPDATE AS OF FRIDAY 5/6/16: The freezing problem has been fixed, it turns out the gpu wasn't all the way in the pcie slot (oops) anyways I will soon be getting a steam controller and as soon as I do that I will install steam OS on the optiplex and it will become a full time steam machine, a $150 console.
So I decided I wanted a second pc as a light gaming rig and I found this trusty old Optiplex 780 off of ebay for $50, I added a gpu and an os and I was ready to rock! Currently I'm thinking of turning it into a steam machine but until I buy a steam controller it will be a general purpose desktop pc. It still has a few issues such as it sometimes freezing forcing me to unplug the pc and plug it back in (probably a psu/hdd issue) and I'm still getting accustomed to the linux way of life but so far so good.
CPU: Four cores but outdated architecture it works though
RAM (6GB): Previous owner added the extra ram this pc has, it's slowed down by the stock memory making the memory sluggish
HDD: Still holding on
GPU: The highlight of the build, small, efficient, cool, and fast it can take on any game I own at 1360 x 768.
PSU: Hasn't blown up... yet
KB/M: Not very good for gaming but it was a simple solution. Works for now
Monitor AKA TV: Doesn't have a brightness setting so gaming at night is painful
Speakers: They work
Firewire Card: Does anyone even use this besides smug hipsters who read gameinformer magazine? It's so irrelevant that I even forgot to include it in the part list!
OS: Pretty good so far, still getting adjusted but it is going smoothly, I may switch to steam os and turn this computer into a steam box in the near future though.
Great bang4buck card for people looking for a small single slot low profile card that doesn't require a 6 pin power connector and still has great performance at 720/1080p. but if you have the space and the power I suggest you get a 950 or r7 370.
