That article is incorrect; their guess of equivalent GPUs was about $5600 too high. The FirePro D700 used in the Mac Pro was essentially a rebadged consumer card. (It's surprising, but none of the GPUs in the Mac Pro officially supported ECC.) Instead of two FirePro W9000 cards ($6800), they should have specified two HD7970 6GB cards ($1200).
