Thinking about picking up a 3.0 Mac Pro. I had a few questions before I do. A) Is it worth buying it now or is there a chance that they'll be updated at the WWDC? B) Hardware RAID vs software RAID. I plan to do a RAID 0 setup, and didn't know if there was any speed benefit to purchasing the RAID card and having that run the setup as opposed to running it via software implantation. C) I hear conflicting reports, 8800 or 2600 for the graphics card, which is superior for core imaging? Any help on any of these questions would be great.
