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
cgminer --scrypt --gpu-engine 1100 --lookup-gap 2 --temp-target 78 --temp-overheat 80 --temp-cutoff 85 --gpu-memclock 1500 -I 20 -w 256 -g 1 --thread-concurrency 21712 -o stratum+tcp://stratum.give-me-ftc.com:3333 -u [removed] -p [removed]
