Some advice..
BFL 300gh card is $1,200
If i order one and mine for lets say 6 months I could get anywhere from 2-X btc..
The ROI is not a problem and im not looking to re sell this card simply a way for myself to get some BTC for the long run without just purchasing 1.2k worth?
I will hold the coins until later with a hope of a spike and if Bitcoin dies out which i don't believe will happen.. Then whatever right?
You need to do more reading. If your computations made sense then everybody would buy the 300GH/s card for free money, then the difficulty would skyrocket and nobody would make money. And that's exactly what's happened, except not with BFL hardware. Considering BFL hasn't finished tapeout yet you're looking at a May/June release on those cards.
