bcpokey, people don't have the luxury of building 1.73Mhash/$1 systems anymore. It can't be done.

Maybe not, that was an exceptionally efficient build that I'm proud of, but it still stands that you need to be very efficient if you want to profit, and < 1Mhash/$ is very inefficient. Even at stable difficulty and $20 coin prices, it wouldn't pay itself off for almost 1.5 months. A bad goal to shoot for.

My point isn't to build my build, I was lucky, it was just that you need to be as efficient as possible, and have numbers to approach, if not asymptotically.

You can still build somewhat efficiently, for example a 4x 6870 rig pulling 1.2GHash/sec can be built for maybe $900 if you build smartly. Already up to 1.333mhash/$. There may be other builds that are more efficient, I'm currently amp capped though so I haven't been looking to build more lately Sad
