There is a misconception I see on these forums quite often - that you will make a higher ROI with more GH/s. The ROI is equal at every level. If you have 10 GH/s you will make 0.01443 BTC per month at the current difficulty. At 100 GH/s you'll make 0.1443 BTC a month, which is exactly 10 times the 10 GH/s.

Of course there are considerations of equipment cost and efficiency per watt, but if you're just talking GH/s the ROI is the same. If you buy 2 Bitfurys you will get the same ROI (as a percentage) as you would if you bought 4.

Yes of course the ratio is constant. However, it is only a matter of time before mining with any hardware simply becomes a waste of electricity. I wonder if it would be possible to "force" the difficulty to decrease by coordinating a pause in mining, then quickly mining the reduced difficulty. Then the process would be repeated.
