Your motherboard probably already supports the Ultra ATA133 standard. So, probably not worth it. You will need to use the ribbon cable that came with the drive -- unless you can tell that the old one is using the 80 conductor ribbon. Then again, if your mobo already supports the ulta ata133 standard, you probably already have the ribbon cables and this is all moot.
Now, if we're talking about serial ata then that would be different story since only the most recent mobo's carry support.
