Hmm, I'd like to know how this is possible at an average of 286 Mh/s.  That will generate only 1.3BTC/week (that's every 7 days).  To generate enough money to pay off the card ($130) it would take you about 7 weeks.  Maybe this used to be possible, but it's not anymore 

Let's say I purchased 3 of these things (enough to populate one motherboard), well that would theoretically do the job 3x as fast...

So we're making 3.9BTC/week.  At this rate one could pay off one card every 2.3 weeks.

I think that means since the days when a HD 8350 could pay itself off in 2 weeks, the difficulty has roughly trippled.
