Tweaktown has a video of a little graphical insanity for your viewing pleasure.  They’ve taken four MSI HD5870’s and made some custom heatsinks of a rather impressive size for each of them and placed them on an EVGA 762 4-Way Classified motherboard with a i7 980X overclocked with LN2.  They take you through the setup, including a nice tutorial on adding a custom heatsink to an HD5870 and finish up with some rather impressive runs. 

“Four 5870’s in CrossfireX with an overclocked gulftown CPU is a monster setup in anyone’s book; and they would be right. But I say NO! – We want more and by more, I mean more drama, theatrics and excitement. So, it’s time to bring out the soldering iron, strap on more copper than can sink a small boat and really get these cards pumping.

For some time now I’ve looked forward to some five-pot action; that’s liquid nitrogen containers on the CPU and one on each of the MSI 5870’s. But one hold up, or should I say hardware failure after another has made this long overdue. At long last those false starts are behind me and I am finally ready to let this monster setup loose.”
