x800 is the best value if you don’t intend to run a 30″ Cinema Display. Also, ATI was offering a $50 rebate to North American users who upgrade to an x800 and turn in their old video card.
If you want to get a 30″ CD then get the nVidia.
If you’re planning on using Motion a lot, stay away from the Radeon 9800–not enough horsepower.
You should also look into a firewire DV to analog converter box to run the monitor.
