Is it more efficient to use multiple computers when I have multiple GPUs?

3

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:

  1. ~1900 MH/s on one machine
  2. ~1200 MH/s and ~700 MH/s on respective machines
  3. It does not matter

Could the answer please include efficiency for both solo mining and pool mining?

More efficient in terms of Hash/Second, Hash/$ or Hash/Watt? – Nick ODell – 2013-04-23T00:23:48.863

@NickODell I reworded the question. – user4543 – 2013-04-23T00:43:30.700

It doesn't matter. Every hash has an equal probability of finding a block. However, that being said, there's some hidden teeth:

  • Putting graphics cards together will make them harder to cool.
  • Putting them in multiple computers will use more electricity - all computers use some electricity, even at idle.

Could the answer please include efficiency for both solo mining and pool mining?

My advice applies for both.

If I had a solution for the cooling problem, would you consider having 3 cards in one box to be the best solution? – user4543 – 2013-04-23T01:07:11.023

@user4543 Yeah. – Nick ODell – 2013-04-23T01:12:15.183
