Thank you for providing that calculator! Taking all that into account, I'd be better off buying 2 5850s (Found them for $125 after shipping). I could pay off the cost of the cards in a little over a month! Albeit the net gain isn't as substantial...I could still make a profit!
Any idea what the growth rate may be after these few months?
I suggest you follow your own calculations, and don´t believe a word of your direct competitors.
too many shameless biased opinions ...
