When I first looked into the market of getting a new computer, I was considering both pre-builts and a gaming laptop.
After finally coming to my senses, I set about putting together a parts list that would keep my budget low, but still let me play modern games on High-Max settings. (Lets be fair, I waste most of the power on playing Kerbal Space Program.)
I had a little trouble getting the AMD Drivers for the 280X to play nicely, but once that was resolved, I've had no problems since. I would like to get a bigger motherboard that might support Crossfire in the future, but for now, this is a pretty solid little build.
I haven't run any benchmarking yet, but have been able to play KSP, Skyrim, Euro Truck 2, and a couple other games on Max without any issues at 1080.
Cooling for this case is pretty good, but that's probably not at all helped by my absolutely abysmal cable management. Everything was just stuffed into the case to get the thing working, and when I have a free weekend, I'll spend the time making it look pretty.
