I am running the 7870K with a crossblade ranger.
I DID experience infant mortality in two of them, before I got a third that has worked fine. Just full disclosure for the sake of completeness. 2 rangers would not post after a BIOS update. THUS, if it's practical and you have a local vendor, go ahead and purchase there so if you get a dud you can exchange it via the vendor without doing the mail order "return and wait" game, ASSUMING that would even happen.
Again, NOT MEANT TO DISSUADE you from this board. These are complicated, mass produced electronic devices, and "stuff" happens. I used to be a reliability engineer in a previous career, can you tell?
This being said, I would say don't let that scare you off, by any means. I am very pleased with this MB.
Only other advice I will offer: Don't skimp on DIMM quality and make sure you buy a matched set. This thing appears very touchy wrt good memory (i.e. requiring it).
It is feature packed, and I like it very much. That is my recommendation for one option.
