The only problem I have run in to, is that when I try and overclock my GPU, as low as +20 on the core, and then running the simplest games, like Garry's Mod, makes the screen go black, forcing me to restart my PC.
Graphics card was bought from a friend who didn't have enough juice to run in crossfire, it replaced an R9 270X. Display, Spinpoint HDD, and optical drive are from previous OEM HP desktop. SSD and wireless card were birthday gifts. All other prices with no vendor listing were bought from either Best Buy or NewEgg during sales and/or had rebate cards that are no longer available.
