Happy reading then. I have no further interest to answer you with such attitude

1 - It's not worth at all with this card. At the current difficulty and stock prices you would eran around 30 US Dollars a month. Here's the calculator - http://www.alloscomp.com/bitcoin/calculator.php

2 - Probably yes, but like I said it's not worth it.

3 - They are all equally simple/hard to use. There is no installation. It's just a binary file and using Command Prompt you run it. There are also GUIs, but you don't really need this for the mining itself. All Miner programs have their respective official threads in this forum. Just search for it.

4 - In your case, they are all equally worthless.

5 - The value of each block is not increasing, but the opposite - decreasing with time. Currently 1 block is valued at 50 BTC which will half down to 25 BTC in the near future. It's all very dynamic and there is no way to predict future profitability or bitcoin prices or even difficulty. The only known value is the number of BTC produced for a set period of time.

6 - Again, no one can predict that. But even if the price of 1 BTC increases to let's say 1 million dollars that would just lead to transactions using more decimal places - for example 0.0005 BTC. That's the beauty of it - it can be divided down to 8 decimal places, so technically there could be trillions and trillions of individual "coins"

You need to read more info

Btw I just bought it - 1 hour ago.

Now I need to be patient and wait for the components to arrive and then I can proceed to assemble it.
I'll report back if there are any troubles

Final Rig:
Gigabyte GA-770T-D3L
AMD Athlon II X2 250
4x 1GB XFX HD 5870
Corsair HX850W
Kingston 2GB 1333MHz DDR3 RAM KVR1333D3N9/2G
3x 120mm Coolermaster SickleFLow Blue LED Quiet Case Fan
8GB Kingston DTIG3/8GB USB DataTraveller G3, USB2 Pen Drive
TP-Link TL-WN821N Wireless N USB
3x Riser 1x cards
1x Riser x16


I expect at least 1.6Ghash/s

I am one step away from buying the rig, but just want confirmation I haven't missed anything:

4x XFX 5870
GIGABYTE GA-770T-D3L (has 1 x16 slot and 4 x1 slots)
AMD Sempron 140 2.7GHz AM3 (do you think it might cause 100% CPU usage under Linux?)
Kingston KVR1333D3N9/2G ValueRAM / 2GB 1333MHz
Corsair HX850 - 2 different reviews has confirmed it can output 1000W if needed.
4x PCI Express Riser Card Flexible Cable Adapter PCIe x1
2 x Coolermaster SickleFLow Blue LED Quiet Case Fan 120mm  (will be positioned on top of the cards for additional airflow)
8GB USB Flash Drive to install Ubuntu or LinuxCoin on
USB Wifi Dongle (not using wired connection)


No case, but DIY project
No monitor, mouse or keyboard needed

I would expect 1.6Ghash/s from it when overclocked = 180W max for each card

Any suggestions or comments are more than welcome.
