Nearly 10 years ago a 2.6 TFLOP (FP32) GTX 660ti cost about $300 and had a TDP of 150w.

Kinda proving my point then? Power usage 15x higher and $300 is just for a card that is probably as big as a whole Mac Mini.

Now add the rest of the components and the prices, wattage and size shoots up exactly as described.
