I've used both brands and I can tell you, MSI's support is 10000x better. I was actually able to get a hold of them when setting up my current system and they sent me some extra items to use when setting up the system (SATA drivers since I was installing to the booting SATA RAID). I've kept that spare disk and just use those whenever I setup a system build using that mobo. I've tried giga-byte support before and (as I already noted) they were not even close to as good, or fast, when getting back to me. Granted, I'm not one that asks the easy to answer questions. More like the one that tries all the typical fixes, looks online, tries those, digs some more and then gives them REAL issues.
