I have 4 video cards: 2x 7970 & 2x 6970.
This is a question of efficiency regarding MH/s. Simply, I would like to know which is better:
- ~1900 MH/s on one machine
- ~1200 MH/s and ~700 MH/s on respective machines
- It does not matter
Could the answer please include efficiency for both solo mining and pool mining?
