Nice Thread - yes I did just read all from the beginning - so thought I'd register, say hi, and tks.
One thing I was wondering, there are some posts concerned with efficiency (hash per watt),
is this because they are more interested in increasing immediate fiat returns?
For me personally I take the cards as far as possible with an eye on max mBTC return, even at lower "fiat returns"
Reason I do this is increasing BTC holdings is priority for me, Anyone else have thoughts on this?
Regards.
It's power cost and also allows more cards on a circuit
it makes very little sense to jump your power bill up by 20% for 1% more hashing power or something
Better to just take that money and buy more coins
edit - also will significantly increase the longevity of your cards
edit 2 - and also reduces heat generated, which saves you money in teh summer from AC, increased longevity from reduced temps too
