Nice rigs. I wonder what hashrate you get from Gigabyte R9 380?
With Claymore I managed to get 21.5Mh on my 380X
Is there an advantage to the 3xx series of cards? My R9 280x pulls 22-24Mh mining ethereum so I was thinking of picking up a few more to mess with.
It actually depends on a specific 3xx card.
I've tested the following GPUs with reasonable overclocking params:
370: 15-16Mh
380X: 21.5Mh (With Claymore miner. With Ethminer it was 18Mh)
390: 28-29Mh
