bitcoin is built on a house of cards , as soon as people's confidence is shaken and they loose their butts due to regulators, bitcoin heists, or other unforeseeable events, the whole thing will come tumbling down. Mantle willl be at least 2 years before it will mature, and directx is planning on "closer to the metal"programmability and optimizations as well. I bought my r9 280x for 295.00 with shop runner and 5 % promo code from newegg before the prices soared. It was a great deall compared to the 770 that was 60 bucks more. At current prices I see no benefit in buying Amd for gaming for any card that is artificially inflated for mining.
