SATA uses it's own type of cable. Like mentioned above, if your motherboard comes with SATA, it will probably have one cable with it for each port. Also, most retail boxed harddrives that are SATA will also have cables with them

I second the notion of going with an ATI card. I actually paid $100 or less for my 256 meg ATI dual monitor card. And that was 9 months ago no less.
