2 x 7950 ROI calculations

[coalescent]

Okay,

So I have the chance of getting 2 7950s at a good price (sub-$400 USD for the pair).

However, I am interested in calculating the ROI at the current difficulty. If it's too high given the influx of ASICs on the market, meh...

I'd like to do it based on $0.12/kWh and $0.00/kWh...

Any sites out there to help me with this?

I've always used bitclockers.com calculator, but its more a habit than it being the best.  it should work for you.. be aware that the owner of that pool has been accused repeatedly of stealing miner money, so I would never mine there, but the calculator works well for me..

Looks like 3 months of 24x7 mining to break even with $0.12/kWh.

Mehhhhhhhhhhhhhh.... and that's assuming a fairly high price of $135/btc.

Litecoin calculations are faring a bit better, but still a tough sell for me right now. We'll see how the plan for free power goes down...

I just bought into this with 2 7950s for about 450 and a third I picked up for 40 that my or may not need an RMA.  The way I have it figured is I'll pay for the rig in 2 months if 3 cards work.. 3 without... and if it doesnt work out... then I'll still have about 500$ worth of cards so its really no harm in trying. 

I'm thinking I'm gonna do litecoin though, seems to be a bit more money it in for what I have.
