Greetings, I will be purchasing a W3680 CPU to install in my 2009 Quad Mac Pro. I just have a few more final questions before pulling that trigger. 1.) I currently have 1066MHz RAM from OWC. From what I can see in previous posts, the 1066MHz will still work? 2.) Is there anything else I need to prep for besides getting the 2010 Mac Pro firmware to work? 3.) My Mac Pro still runs Snow Leopard. Should I update to Lion before I do this? 4.) Lastly, lets talk SSD drives. My primary purpose for this machine is video editing in which my media is on internal HDs and firewire 800 drives. If I upgrade my OS drive to a SSD, but still use traditional HDs that have my media on it, will I see any speed increase?
