From what I can tell from the table and others' experience, 300-400MH/s per card would be doable, no? I guess time will tell!

BTC for about a month then probably LTC and converting them to BTC to cash out
Right now BTC mining is on par with LTC as far as income. If LTC difficulty keeps going up there would be no point converting, just stick mining BTC.
I'm getting around 350-360 KH/s on my 7850 mining LTC.
You won't get 1300MH/s unless you run 4 cards.
You can get 900MH/s easy, 1000MH/s if you push it more and don't mind it crashing now and again.
Only 1xPCI-E each, 100-120w per card, 750w is more than enough.

Which coin are you going to mine (it affects the wattage use)?
Putting together a new rig. Using the below. Can anyone guess the expected wattage usage and hash rate?

I've already done the math and it looks like 1300MH/s? Max power usage would be about 750W. Anyone see any issues with these numbers?
