I used to have to play counter strike at 60 fps and I needed an upgrade. It took 5 months or so to build this and now I'm getting 400-500 fps and its great.
One huge regret I have is not getting the 6600k. But the non-k is working just fine.
Peripherals were both easy choices. The G403 is the best FPS Gaming mouse according to yt.com/RocketJumpNinja, and the keyboard was non backlit with Cherry reds. Both I am satisfied with.
I have not purchased the 144hz monitor yet (going to go with the BenQ XL2411z). Don't mind the monitor I selected at the bottom.
