What chipset? I assume K7VZA is KT133A? I have found the ECS board I chose for my first Rig to be very good, if not lacking in Ocing options. I bought the K7VMA (KM133, needed integrated ProSavage). Good mobo, no problems at all except that the on-board ATA/100 controller refuses to recignoize the ATA/100 cable so my drive is @ ATA/33 but other than that very good board.
