Yeah looking at my recent cost I spent about £400 odd for a 6 card, 1kW base unit, before the cost of GPUs is added.
but its not just that its physical space that has a cost
10rigs suddenly having to be 30rigs, 100 having to be 300
this is why the smaller cards are not popular for miners
if nvidia brings in a card thats twice the price but also twice the hash using the same power/hash then yeh i can see them being bought up
but these just make no sense
