Two 3GB GDDR5 Sapphire 7950 Boards

FTC Pros, question for you: how many FTC do you estimate a rig with Two 3GB GDDR5 Sapphire 7950 Boards will produce per day? The 7950s are stock. No overclocking, undervolting or any of those tweaks. Thanks!

You should get around 1.1-1.2m/hash = around 51 ftc per day

Indeed - possibly a bit more. These cards can pull 600 - 650khs each with the right settings. Happy days!

I can tell you exactly how much since that is my rig :) I get about 1.0 -1.1m/hash not over clocked. With over-clocking it is closer to 1.3-1.4 m/hash. I am currently using these http://www.newegg.ca/Product/Product.aspx?Item=N82E16814202026
Good price too.
I use afterburner to give me a 10% power boost and use these settings:
timeout /t 30
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
title CG_MINER_01
color 02
