I also have had an MSI. Was a great board compared to the ASUS piece of crap is replaced. MSI IMO is mid-range boards as in it's not just absolutely nothing in the BIOS and option all around, but it's not just jam packed with them either.
But that was in the K7 models mainly, the K8 I noticed they had a LOT of BIOS options everything you'd need to OC and even stuff you'd never use.
