Hello David, Sorry I don't now the answer to your question but I saw your post and wanted to make a couple of questions.

Are you running two 7950's or how many?

How big of a power supply do you use?

I know that GPU mining can not always be worth it especially with BTC unless you get cheap or free power. What is your power situation? Do you live in an apartment with free electricity?

BTW all the lights are pretty.
