The ABIT NF8 comes with just a SATA 150 controller. Unless you wish to use raid on your computer you would see very little benefit. Your hard drive is probably and ATA133 standard and SATA 150 is just marginally faster.
' and is it as simple as using the SATA cable to connect to the motherboard? or does the drive or board have to be configured etc? and is this complicated? '
It's usually as simple as that. Plug in the data cable and plug in the power. You will probably have to load the SATA drivers but you can do that in windows or when loading on an operating system.
