i want to use a WD Raptor in a new build but i am not sure if the mobo i want to use will work right so i guess my question is this. Will a HDD that uses SATA 150 work in a SATA 3 mobo, or do i have to get a mobo that has a SATA 150 connector to use the Raptor?

To ensure seamless backward compatibility between older SATA and the newer faster SATA 3.0 Gb/s devices, the latter devices are required to support the original 1.5 Gb/s rate. In practice, some older SATA systems that do not support SATA speed negotiation require the peripheral drive's speed be manually hardlimited to 150 MB/s with the use of a jumper for a 300 MB/s drive.
