I currently have Gigabyte 55 Plus S3 motherboard from around 2005-2006 that has a rear 1394 port. But it seems my board has crapped out. It uses an AMD Athlon II cpu. What other Gigabyte motherboards, possibly from a later time frame, has a rear 1394 port, 2 PCI-E slots, and can re-use my cpu and memory? I don't want an add in card option or usb header option. It's currently running Vista 64bit. Can anyone suggest something for me?
