Alex, it's good that I didn't see your question last night, since any answer I would have attempted would have paled in comparison with Mike's knowledge in this area.
I'll add that if you do decide to get the Integra processor instead of a separate video processor, you should note the test of the 80.3
here where they were especially impressed with the new HQV Vida video processing. It may be that any slight edge the best separate video processor might still have over this wouldn't be visible on your setup.
