Most system builders can build that machine - the CPU shop down the street from me is offering basically the same system (with a 660 instead of the 690) for $1300. I can upgrade to the 690 and it would still be less than $2000. The system I have speced now has a GTX 680 but a 256GB SSD for the boot drive, all for $2000.
This system is about 3x faster than the one I built 2.5 years ago. And for the same price. Amazing.
