Was your budget completely expended when building that ~$900 rig?
Why not start out with 2x 58xx?
Do you have capital to apply towards the card(s)?
Can you rework the payback formula to show 50% - gaming time - elec from btc earnings so we can see how much cash you will be paying out of pocket each month?
What is your source of income now to pay back the out of pocket portion?
cheers
Edit : Taking that into account, by the end of the period, the loaner would receive 90 Bitcoins by the end of 6 months. If the loaner has loaned 100% of what i am asking for, that would make him short of 10 bitcoins. As per my previous post, the loaner will receive 100 bitcoins by the end of 6 months being the bulk of the loan will be settled by the end of the 6 months. This would of course vary, depending on the interest that is imposed by the loaner.
Thank you for taking the time to answer that so thoroughly. I am confident you are sincere in your request. Now we just gotta improve that model a hair so 6 months does not kill you and the loaner. ;p
The other benefit to acquireing a 5830 or 5850 is that you can add another one in just a few months and then can later sell them to upgrade further. I think the catch some people are missing there is your location. I assume that makes it a bit harder or more expensive for shipping from other places?
Hopefully goat gave you a good offer. 2 of those 5830's would give you ~630MHs and cost 1/3rd of a 6990
