Hello,

I like to get mining and got 2 questions I cannot seem to find answers to, hope anyone of you can help me out.
I got 2 identical PC's I can use for mining, I need to get VGA cards and from my research ATI 5870 GPU's seem to be the best value for money.

Questions:

1. Is there a prefereable brand of card to use or will any 5870 be ok? Linux miner)
2. Will 1 PC with 2 5870's mine more than 2 PCs with 1 card each? (assuming there is no difference in power consumption)

Thanks in advance for any help.

Got an answer to question 2 from here: https://www.bitcoin.org/smf/index.php?topic=7733.0
better 2 cards in 1 machine because performance is the same but no extra PC overhead (electricity).
