I'm going to take it back the 7850 is still a good card for mining. I'm able to get 340 KH/s on my 7850 that means when four I could get 1360 KH/s at $125 each that is $500 and now you can see why I went with the 7970s I got for $520. I get 1400 KH/s with them an I can under-volt them to save power.

Thanks for sharing this with us.
well CPU mining is OK if you mining only CPU mining cryptos (like PRIMECOIN ...), and you have i7 or large numbers of computers
sounds like good advice but as I only cloud mine at CSX.io what do I know?! The bit that I do know for sure is right

Does the amount of coinage you can generate for yourself via mining go up or down depending on the current value of the currency?
This is determined by the 'difficulty' of the coin, which fluctuates depending on the rate at which people mine it. The value of the coin is somewhat correlated with difficulty - coins that are harder to mine have a better value, which is why coins that pay out lots of rewards are worth the least upon starting. This is a basic principle and there lots of other factors that influence the coin's worth too, like the release, community reception etc. Have a gander at http://www.coinchoose.com/ and note the patterns between the number of blocks, coin reward, difficult, and BTC worth
Balaks,
No the amount of coinage you generate is based entirely on the mining difficulty of the coin and your equipment. Check out dustcoin : http://dustcoin.com/mining. Since mining Bitcoins is kind of difficult with high barriers to entry many people are mining the alt coins like Litecoin and trading for Bitcoins on an exchange. Since the price of Bitcoin is going up due to the current bubble your converted Bitcoins can be sold on coinbase to USD.

I am still struggling to understand the process involved in mining, but would like to give it a try - I own a tiny value of bitcoin and a reasonable about of some alt-coins.

M3gaman,
No only mining scrypt because 256 is way to difficult.
All,
I did some tweaking yesterday the video cards are voltage unlocked. I was able to increase the hash rate to 1340 GH/s with the top card running at 76 degree and the bottom at 66 degrees. My Kill-A-Watt registers the reduced voltage as well to a reduced total power draw of 560 watts at full load. I think I can go lower if I had a better power supply.

Same hardware is used to mine 256 coins and Scrypt coins?
All-
An update. So I installed the two 7970 Sapphire Dual X video cards and undervolted them a little. They are pulling 666 watts from the wall. This is kind of high for a 650 watt power supply so I'm thinking I need to get a new one. Out of the box using CGMiner I get 1250 KH/s at 80 degrees for the card on the high slot. My girlfriend made me a deal to pay the electric bill with my coins so we will see how that goes. I'm thinking of trying Reaper in the future to get 1400 KH/s but right now I'm happy with the results.
I could use some advice on the power supply.
What is a safe undervolt to use on the 7970? I have it set to a GPU Volt of 1100 MV
Thanks for your help

Reannypleas,
I agree if you already have it. Very hard to find. There are some other cards that will work as well. I went with what is a nice video card at a cheap price today.
Thanks

Don’t mine if you have something lower than a ATI 7850
ATI 5850 works well, these cards are cheap and with low electricty costs slightly profitable
All-
Thanks for the replies. I wanted to provide some feedback.
1. YES mining right now is a good rush and the general stores (Newegg, Frys, TigerDirect, ASIC manufacturing are making all the REAL money)
2. Here are the websites I mentioned
Middlecoin.com
www.multipool.in
3. bittech9438 (You sir are awesome)
The P3 - Kill A Watt device will tell you your TOTAL draw it is a cheap must have device in my original post. I got 2 x Sapphire 7970 Dual X OC with boost mainly because I got them at a good price and I wanted them anyway but because they have working profiles that get around 700 kH/s. Also I just read they are voltage unlocked and I can use MSI Afterburner to do so. What is the lowest voltage I can go?

• Don’t mine for Bitcoin (waste of time)
Lol, depends on price of equipment. For first Avalon users = golden mine. But you must buy the ASIC cheap to be profitable today
On mining efficiency:
One other thing that I've found with tuning the cards is to optimize for power efficiency. Make sure you get cards with unlocked voltages so you can do this. I've been able to lower the power usage of my 7950's from 225 watts down to about 175 watts under full load while still getting good hash rates. The cards are most efficient when running about at or below stock speeds but undervolted (.962v instead of stock 1.25v). You'll also need a kill-a-watt meter to measure power usage at the plug if you don't already have one.

This is great post for all wannabe miners. I think that people need to read and learn first, and then to mine.
Thanks for sharing your discoveries on mining as well.
I've found that the Litecoin Mining Hardware Comparison page is super helpful for evaluating video cards and rig configurations. It is here: https://litecoin.info/Mining_hardware_comparison.
Also don't forget to factor in the energy costs of the PSU efficiency and the power costs of the overall computer as well into your calculations. I like 7950s for mining, particularly the Gigabyte 7950 - GV-R795WF3-3GD and the Sapphire Vapor-X 7950. I like to buy these at a discount for about $200 a card from ebay, craigslist, newegg (with sales) and amazon.
Good luck!

Middlecoin do you mean middlecoin.com? Thanks for share.
I noticed the outcries of some (latecoming) miners, but haven´t realized it is this bad. It resembles alaskan goldrush, where the most proftable weren´t miners and adventurers but merchants who sold guns and shovels 
or in this case - ASIC manufacturing corporations and exchange owners.
