This was my first build and was an attempt at a gaming PC. I made a few mistakes- I got the 2600 instead of the 2500k, I got way too much ram, I have zero cable management, but that's all a part of the ride. I got this rig for about $1000 before tax, by buying the pieces slowly over the course of half a year, when they went on sale. Over all, I am very happy with it, as it can run Crysis at very high settings! I couldn't have done it without the help of /r/buildapc and my very tech savvy friend Daniel.
Also my graphics card is the 5970, not the 5870, but PCPartPicker didn't have it as an option. :)
