I use this machine for recording minecraft at a 1080p resolution. It runs well @1080p with shaders and I'm going to test Watch_Dogs soon. Everything worked well together, its my first build ever and took me a while to put together but everything worked and I followed proper precautions. Definitely looking forward to playing & recording for my YouTube channel https://www.youtube.com/user/KeenWolfPaw
Edit: Ok, since it's been quite a while since the initial build of the PC I'll start explaining some problems I've noticed with this build.
1) I can't seem to get the monitor to wake when moving the mouse, a quick Google search lead me to reading that I needed to disable PLL overvoltage, which leads me to my second problem.
2) The BIOS is hard to get around, with little documentation or support. Still haven't found how to disable PLL overvoltage if at all possible to do so.
3) The CPU stock fan gets quite loud when doing anything super intensive (rendering videos), that's a flaw with the build itself and I would need to buy an aftermarket fan to avoid this to a degree. Of course, you can't really expect a quiet fan when stressing the CPU so much.
Watch dogs ran fairly well for a game believed to be so resource intensive. I would average around 60FPS I'd say on higher end settings, with minimal stuttering. It wasn't too loud when running the game either, although the fans would be the quite loud after playing the game for a couple hours straight.
