Just made my personal rig with a $1700 budget (in Australia) with links and all that to where I got the components. Perfect if you live in the Melbourne area as you can just pick the components up rather than ship them. Its as cost effective and powerful as I could make it.http://www.tomshardware.com/forum/348979-31-1700-gaming-build
If you want the the GTX670 you could cut out the fans,LED strips and Fan Controller from the build. Its an amazing rig so far.
