Model numbers are a good identifier. Not all 7950s are made equal. I get 600+ on my Sapphires and recommend them in my build guide at
http://www.coinminingrigs.com. Do you have them set up and mining yet?
I do not have them up and mining. My wife does not want a milk crate set up. She is concerned that my 4yo will get into it. So, I'm going to order a haf x cooler master, otherwise I'm going to follow the guidance for to graphics cards shown on your website. Thank you for putting that up by the way.
