My first computer build, wanted to design a solid gaming computer at a good price. Followed one of the builds listed here: http://elitegamingcomputers.com/good-cheap-gaming-computer-builds-for-2013/. I'm aiming to turn around and sell this one locally, but I wouldn't mind hanging on to it!
It runs games like Skyrim and Planetside 2 at highest graphics without a hitch. I know the weak part of this build is the CPU, but at $100 you can't beat the price. As mentioned, it runs new games flawlessly, so for now, at least, the CPU is a deal. Being AMD, it could also be overclocked. The mobo can also run AMD's FX series, which can be overclocked nearly to the power of an i5 (or so I've read...).
Anyway, it was a fun experience building it and playing games is pretty eye-popping!
