Given that entry line and enthusiast AMD gfx cards scale in their mhash per Watt, I see zero argument / sense in differentiating between "hobby" miners vs "pros".
How could there be? The MARGIN stays the same issue regardless of how much VOLUME you have.
If it somehow becomes unprofitable for the current AMD generation of gfx cards, it becomes unprofitable for _ALL_ of them.
Regardless of whether it is some dude running 10 machines of 6990s or one normal guy with a 5770 - setting aside other hardware components / power draw sources, of course.

You're focusing on just the cards, not the infrastructure, power costs, or labor... If you're paying $.25 per kwh and I'm paying $.08 kwh... things become unprofitable for you, way before they do for me.
Also scale as well... if you have 1 machine making $1 USD a day profit... it might not be worth the headache.... but if I have 200 machines making $1 a day profit it might very well be worth the headache.
As soon as it gets to $1 a day per machine I'll be out of here. That's how much it costs per machine, if each machine uses the full wattage available to it. I know that is unlikely as there is actually very little in the machine, but it's always good to have a limit set for my escape
