3) To echo other people. 30% cooler and more energy efficient that mining scrypt is a huge bonus also. More eco friendly, and saves miners money! I know I sure appreciate only pulling 500W at the wall, rather than 800-1000w I was pulling before.
Thanks again for your work! I'll send some coins your way.
It's more than that !!!!!!!
I'm runing 2 rigs with a total of 9 x R9 280X, it was pulling 2420W on SCRYPT mining.
Now it's only pulling 1180W and it's runnings 2 times cooler : so 50% economised !!!!!!!!!!!!!!!!!!!!!!!!
