ABIT AB9 Pro Intel P965 Express Motherboard Review

ABIT AB9 Pro Intel P965 Express Motherboard Review - PCSTATS
Price Check: $/£/€
Abstract: Since we're dealing with the Intel ICH8R southbridge, SATA RAID 0/1/5/10/JBOD is standard. Of course there's more to the AB9 Pro than just Serial ATA, this Socket 775 Intel P965 Express based motherboard has a lot going for it.
