Just to put it in a bit of perspective, the processor alone on the 6-core machine costs ~$1500. The graphics cards on it are ~$600/ea. You're at nearly $3k right there with just the actual CPU and GPUs themselves. Factor in the RAM, SSD, mobo, custom cooling setup, case, etc. and the price they're offering it at isn't that outrageous. The biggest issue that comes into play is the gap that Apple has created now. There are lots of pro users out there who would love to have that processing power, and yet, they don't need those insane GPUs. They're forced to either stick with an iMac or shell out big bucks for this new Mac Pro and never utilize it to its full potential.
