Like many 2009 MacPro owners, I took the leap and upgraded my firmware from a 2009 MacPro to the 2010 MacPro: http://forum.netkas.org/index.php/topic,852.0.html
After upgrading to 10.6.8 a quick check in system profiler revealed the RAM I purchased from OWC wasn't 1066 DDR3 RAM and is actually 1333 DDR 3. My ECC is disabled as I'm running an i7-975 CPU(yes it works flawlessly) along side a Radeon 6870 GPU(thanks to Cindori for the package)...
Looks like my RAM purchase was future proof after all!
