This. Why not take precaution ? Is that hard thing to do for amd i wonderSure, but in the future AMD should take precautions not to put every egg in the same basket; they could have added a GDDR5X backup version in case of longer than expected lead times and released those as the "low-end" SKUs to compete with the gtx 1070 and kept HBM2 for GTX1080+ performance and up.
