I would looking to buy an power supply with atleast 850 watts. 80% efficiency perferrablly(bad english) but you know what i mean.

My current rate of mining:
80Mhash/s

Amount of BTC mined in a day:
0.185 BTC

Amount of BTC I will make in two weeks
2.59
------------------------------------------

The rate of the Radeon 6990:
700Mash/s

Amount of BTC mined in a day:
1.619

Amount of BTC i will make in two weeks
22.666
-----------------------------------------

Conclusion at this rate my investment of a Radeon 6990 that I'm currently renting for $80/month will have to come to an end before I even started mining with it. By the time that i mine enough BTC to purchase power supply I'll have to spend that money to rent the video card for another month which in turn im stuck in this black hole becuase I'll never mine enough to get a power supply. As you can see with my results that its highly profitable to work something out, I purpose 15BTC which at the current rate of $16.951 would come out to about $254.25 so you figure the cost of the power supply $150+shipping to in the USA($15) = $165;

Cost: $165;
Net-Profit: $89.25;

Not bad if you as me for just shipping something off and waiting for money to pop up in your bitcoin account.

I was looking in the $100-150 range, I was thinking about taking out a loan for $120 to get an 850watt power supply becuase I just rented radeon 6990 but i have a month to pay it off and at the rate my current video card mines i will just break even for the next monthly payment. Any ways I thought some one might help me out by having the option to pay the power supply back with the earnings i make as soon as i generate them from mining until i have fullfiled the price me and the lender agreed on. I would like to keep the bitcoin flow going instead of cashing out in usd i can buy a product with bitcoins and help the lender as well as myself gain trading trust in the bitcoin communty.

I figured out after the difficulty change that i should make around the $500 range more then enough to pay the electricity($95), the cost to rent the GPU($82), and the cost of the power supply($150) and I only need t to pay both of those at the end of the month So I can start payment as soon as i start mining
I can supply what little btc i have right now as collateral.
