I have no experience with the X1000 or X5000.

I would imagine the G5's would be faster since they support altivec and they run at a higher clock. A 2.7GHz Mac plays HD media very smooth, not sure how that translates to the X series...

When the new drivers are released the X series will be a great test platform to compare against the G5's.
