Ya, sorry, I'm not in agreement with the 600/1200/1800 format. Once you get passed a $1000 budget, a person's ability to pay increases more than that sub-$1000. The difference between a $1200 build and a $600 build is double. The difference between a 1200 and an 1800 is not. More commonly you'll see builds nearer the $2400, $1800 builds are same ballpark as $1200 builds. You'll see $1200 caliber builds, with nicer motherboards, bigger SSDs, a bigger power supply, a better case, and it's right up there at $1800.
