Does anyone know why Sapphire is the goto brand for mining? Have a number of Sapphire RX480 (£240) but out of a batch of 12, 2 of them are not that good, constantly crashing. I am thinking of getting the ASUS AMD Radeon RX 480 STRIX 8GB version which is £220. What are the performance compared to Sapphire? I am getting roughly 300h/s on mine.

How about 8GB Asus Radeon RX 480 DUAL OC which is £190
