Do we all agree that this rig at 3Gh/s would net about 55 Bitcoins in a year at a 2% difficulty per month increase?...according to the calculator I used.

So, an approx. $2500 investment would bring back about $7500 in a year at $136 price of Bitcoin at the time of this post?

Is this how the math should work?

A true Newbie question.....

Not quite but you have a grasp of the miner's dilemma. Difficulty will not increase at 2%/monthly since ASICs are hitting the scene. Explore alternative cryptocurrencies like PPCoin or Litecoin. Expect them to flood with former Bitcoin miners as ASICs continue to penetrate the market.

My time is worthless I guess haha Grin

'Tis a miner's life! I just think about how lucky we got it compared to San Francisco 1849, they had to give up air conditioning and consider the idea of spooning with other men for warmth!

can you share the link of the calculator?

I have 2 computers with 2x 7970 in each.. I have a 1000W power supply an dthe other computer has 1200 W power supply, Can someone help me how much my electricity gonna cost? .30 per/kilowatt ... Is that true that 2 cards my not use the whole power from the computer so lets say 1200W power supply is only draining 600W?

Yes, it is true that although you have a 1200W PSU, you will not draw that amount all the time. Chances are you never will even reach that limit, even for only second. I have 2x7970s (Gigabyte non-GHz ed.) and they each draw about 150W @ 551KH/s mining LTC. Windows Task Manager monitoring reports zero CPU and disk usage. DDR3 RAM usage is 1Gb (out of 4). I'm using cgminer 3.0.0 and Win8 x64. I do only pay $0.07 for electricity so check your profitability, your electric costs are somewhat on the high end of the spectrum. Are you located rurally?

My riser cables aren't marked as shipped yet either! I paid good money for US shipped cables! WTF!!

Thank you to everyone else for the nice comments on my case!

Your case is indeed enviable! I would just take out one pair of 120mm fans on either side to give the hot air a place to escape. I imagine you expected to push the hot air to the middle and then let the GPU fans push down. Like I mentioned above, I have 2x7970s and I just left the PC case open and pointed a desk fan at them, solved all my temperature problems (one was running at upper 80s and the other at upper 90s, not acceptable for 24/7 use). The desk fan uses just .05KWh so it's a cost I can certainly afford especially since I have no other way to cool my GPUs enough at 550KH/s!

I would also check and see if the power connectors on your mobo are strong enough (I suspect they are). I haven't read about anyone having PCI-e problems with your particular mobo, may be something worth investigating. You can always buy custom-made MOLEX-powered PCI-e risers from Cablesaurus: http://www.cablesaurus.com/.
