I have poured hours of research into this build, and I can presume that I have wisely chose the parts. Build performs beautifully, plays Crysis 3 on ultra with AA on 4x and post-processing on medium. Can play BF3 on ultra, while recording on 64-player maps, I can't really ask more from this.
Got the CPU at microcenter when it was on sale for $170, very cheap. Also got a $40 discount on the MB, making it $50. On top of that, I got the RAM for $50, and mind you it's some pretty good RAM. I don't really have plans for overclocking, but the CPU and MB was so cheap, I couldn't pass the offer. I hope you all coincide with this.
The build listed below has some mistakes, I got the Western Digital 1TB Caviar Blue, although there's hardly any difference between them.
The GPU was carefully selected, the most bang-for-your-buck GPU I could find. It's listed as a 7870, but it actually performs close to a 7950.
Again, the build below isn't accurate, I haven't purchased the HAF 912, I got the Cooler Master Storm Enforcer. I would say it is better case for the same price. I also purchased on a sale, $20 off the original price. Have no regrets, really like the cool LED's. I got 2 red Sickleflow's, moves a lot of air but is kinda noisy. I don't notice when I'm using the computer, but when I'm downloading during the night, it gets annoying.
The PSU was kind of a poor choice, the non-modularity was very annoying while doing cable management. I've done really poor on the cable management, and can't really do much about it. You see the line cutting across the GPU? I couldn't route that behind the case because the line was too short. Alas, the temps are fine, so worries there. And plus the side window doesn't show the messy cable management.
All in all, I am really pleased to have purchased this, $715.
