(I had 12 58xx's heating up my room for 9 months)
Which type of 58xx did you use???
12?!? you are kidding me
4x5850's
8x5870's
I had a friend build them for me, so I can't remember the MB's used (I'm not that technical when it comes to hardware). But I had 4 motherboards populated with 3 cards each.
It was fun, hot and profitable while it lasted. lol
