Great, what is the hash rate of all these put together and how much do you earn when you run this per hour, please approximate it in USD.
The miner produces 3 MHash/s (each graphic card adds 500 KHash/s).
Profit depends on the coins you mine and the cost of electricity.
This will fetch me around $5 per day, that is if I am lucky to have a good scrypt to mine and from what you quoted your selling price will not be less than 1000 euro.
