I think it's more a matter of personal preference. OCZ fans stick with OCZ, Mushkin with Mushkin, etc. I just picked up the mobo yesterday, along with a core i7 930 and OCZ 1800 8-8-8 6GB. I've used OCZ a lot in the past so I kinda like them, though I was interested in the G.Skill RipJaw 1600C6 or the Mushkin Redline 1600C6. I couldn't find any in Canada though. I picked up the OCZ kit for $200Can though, so I'm happy.
I hope I don't hijack your thread, but I'm curious about how to overclock this thing. The capabilities of this mobo are insane. I OC'd my last evga 780i pretty easy. This thing is really complicated.
