I have just upgraded to a WD Caviar Black drive capable of 6.0Gb/sec transfer.  Does it make sense for me to add a PCI Express Sata III controller to utilize this transfer speed?  Or is there a limitation in my mobo that will just "waste" the extra transfer speed.  How do I test the current transfer speed of my hard drives?

Harddisk are barely fast enough to do SATA-I speeds, so who ever made you believe SATA-III harddisk are faster lied.
You can buy a controller if you want but it won't go any faster.

If you want speed from a drive, go SSD.

 I'd be willing to bet money that it's no faster (read/write/access time) than my WD 500 GB Cav. BlacK SATA ll and it's just barely faster than my 5 year old 250 GB Cav. Black.

'Capable of' doesn't meant it is 'able to'.

Mechanical hard disks are limited in their transfer speeds by their own physical actions. SATA 6Gb/s is pretty pointless for mechanical hard drives as they are simply not fast enough to utilise the bandwidth available. So no, there would not be any performance increase even if you added a SATA 6Gb/s SATA controller card.
