I'm running 3 - 7950s (~625Mh/s ea) on a 1250w 80+ Gold Seasonic PSU and my wattage is hovering around 1050. Kind of makes me nervous about adding another card but I know those 3 are very overclocked (around 1150 & 1600) and could be pulled back in the event of another GPU.

Thank you for offering this to everyone - you guys are da bomb

I completed my first mining rig about a month ago (4 x 7950) and have been mining 24/7 since I got things going. I'm right at 2.4 GH/s, and to be honest, I'm fairly underwhelmed with my payouts. I've been mining in Slush's pool and the dramatic hash rate increase has really slashed my per block earnings. It's not just Slush though. The worldwide hash rate has gone up a dramatic 40,000 GH in the past 30 days, and Slush's pool is up 50%.

I would do some serious pondering if you are concerned about investing in a GPU rig. I have no doubt you will make your money back, it's just a question of how long.

You could, of course, try my approach. Just keep telling yourself it's a hobby until you're out of the red.

Then you can tell your spouse or friends how invisible coins paid for your computer.

Uncle Sam sure seems to think so... but what he doesn't know won't hurt him 

nice!! Good people still exist  

The fact that the thing looks identical to the bfl single seems super sketchy to me.

Second red flag is the super low availability. 500 units? 

I'd stay away.

derp

hugs not drugs

good luck bruddah 

600w sounds fine. I've got 4 x 7950s on a 1250, so that sounds reasonable.

Don't spend that much on a 7990 or a 7970. You can get multiple 7950s for the same price and better performance.

newb restrictions are stupid. derp!
