http://bitcoin.zorinaq.com/many_pcie/Interesting: this ASUS blog post reveals they sold "six figures" of the B250 Mining Expert. Assuming fully populated (19 cards) it means more than 20% of the estimated ~10 million GPUs in mining farms are running on the B250 Mining Expert.
100,001 pcs is six figures. But many people use these Mb with 10-12-23 VGA.
Lets say avarage is 15pcs GPUs. Total should be minimum 1.5 million GPUs.
If that six figures is 950,000 then everything changes.
