I really want to buy the best deal possible for an extra hard drive for my computer. My MB is an Asus A7V8X-X and right now, I have an 80 gig ultra-ATA Maxtor hard drive. There are several great deals on SATA drives, but I don't think my MB supports SATA--but could I add a PCI card with SATA connections and have it work that way? Or use some kind of adapter? What is my best option?
