8x 290!! I would have that setup too!   however just for curiosity could you put some photo about your mining rig? I'm very interested to know how is set up, it's very hot i suppose..and you have more than 3,5 kw of available electricity in your place, or do you have yor cards in a place that's not you home??

However with that setup you could be considered one of the first wales of MRC! wow!   (just kidding ay!)
