I built this PC in September of 2011, and except for the addition of the Crucial M4 a few months ago it really hasn't changed much.
It's an incredible gaming PC. I love it. I can literally max out any game on the market right now. Crysis 2 with DX11 Pack and Hi-Res Textures runs at over 60FPS. Battlefield 3, Skyrim (tons of graphics mods), Crysis (also lots of graphics mods), GTA IV, Metro 2033, and Far Cry 3 are smooth as butter (60FPS+) I will be upgrading Q2 2013 to Radeon HD 8970's, just to keep the hardware moving forward.
The monitor I purchased is actually a 1920x1200 resolution monitor. It is actually an awesome monitor for gaming and I definitely prefer 16:10 quite a bit more.
I also actually do need the i7 over the i5. I run virtual machines, and use Vegas, Lightroom, Photoshop, and Dreamweaver quite a bit. Same goes for the 16GB of RAM (I just don't wanna hear everyone jump down my throat about how I don't need the i7 or RAM)
Overall the build went smooth and I am in love with this PC. I am cleaning out the dust tomorrow and will post better pictures of a nice clean rig. Oh and it's actually the Sabertooth P67, not Z77. PCPartPicker didn't have the P67 though...
