Anyone in this thread actually running more than a few cards?

I am currently trying to run 22x amd 280x cards. The basement where these are running is now almost 30 degree Celsius. And I'm hashing SHA3 which creates a fraction of the heat scrypt does. Not to mention the amount of power all of this draws. with the 280x's i have a watt to hash ratio of 2,6. So my 5,8kw is roughly giving me 15mh/s on scrypt where as with nvidia rigs (that by the way is cheaper to build) with equal power usage i could get 28mh/s. Anyone who dont see the math why the profit margin is very much in favour of nVidia needs to do a reality check. Because 45kw power a year is not exactly cheap.

This is a game changer! stop being fanboys were in the profit business not fanboy business!

Valid points. Now factor in additional motherboards, processors, memory, hard drives, power supplies (because you can only hook up so many cards to each one), additional racks/space.
