I don't build with MSI, but just built a Z87-A week before last and it's a great mobo, OCs well (temp have a 4670K in it), the client plans to but a 4690K in as soon as they are released, but it OCs better than the Z87 did, better BIOS, runs cooler, saw the same with my Z97 Hero, have had the Z87 since Aug of last year and the Z97 is a good improvement all the way around
