I'm looking to upgrade my hd for faster response time, so I'm considering one of the new WD Raptors and wondered if I would gain performance advantage my current ata Seagate hd without changing to a motherboard that natively supports SATA. I know that the retail kit for the Raptor comes with the adapter card but was wondering if it's better to get a new SATA compatible mb over the card and hd. Is it a huge difference?
My current mb is an 8rda+ btw.
