My one test was a dismal failure at about 26600 Mh but I was testing on cracking phpBB3 hashes when I got that speed, so I will see for sure in a day or two.

Most likely this will be a bad investment though. I can face that but I am going to look for ways to "hedge" a potential loss.

Well, according to the Bitcoinx mining profitability calculator, that hashrate would gross $4403.21/month. Granted, you did spend a lot for your rig, but I wouldn't call that a dismal failure!

Unless I'm mistaken phpBB3 uses md5 hashes (~4x quicker to compute than sha256d) which fits with TCollar saying there's only 12 GPU total (~8GH/s with 7970 for sha256d))...

I hope it's all a big joke...

I am starting to wish it was. But I did take into account the speed difference. We will see in my test tomorrow. I might only lose half at this point if I part everything out on e-bay.
